Mum’s Granny Square Bag. Or, Granny Margaret…
Let’s just start with the sad bit and get it out of the way. My Mum died. I flip between knowing, accepting, and understanding wholly that it was her time to go, and complete and utter surprise that she actually deigned to leave after being so stubborn, ordinarily refusing to let illness stop her.
First and foremost, I saw her as a scientist (she worked in labs since the age of sixteen) and an avid learner of many things. But, perhaps due to the generation she was from, or perhaps just because she wanted to, she also explored arts and crafts and had many strings to her bow.
She made her own clothes until her fingers couldn’t. She made me clothes when I was little, too. And I still have a couple of items that she knitted and crocheted back in the seventies and eighties (I can’t write these as actual numbers, as she would say it wasn’t grammatically accurate).
Anyway, I’ve been going through some of her photographs to sort them out, and I’ve found a couple where she’s carrying a really cool patchwork bag. I don’t know if she made it herself. Maybe? A friend might have made it, or perhaps my Nanna (at one time, her mother-in-law).
Unsurprisingly, I saw the bag and thought, I bet that would look amazing in crochet! And that’s all there was to it. I immediately made a start on Mum’s Granny Square Bag.

Fundamentals of Making Mum’s Granny Square Bag
In the rest of this blog post, I’m going to break down all the details so that you have a recipe for how to crochet a granny square bag of your own.
You can also watch the accompanying video of how I made it, which includes a casual demonstration of how I worked the final squares to join them into a bag shape. Plus, I have an argument with a sewing machine.
I know it’s a lot, but I recommend reading through everything.

Using Leftover Yarn To Crochet A Granny Square Bag
Mum’s granny square bag (or, if you feel that’s weird, you can call it Granny Margaret’s Bag) is made from yarn scraps of cotton DK yarn. I didn’t allow myself to buy any new yarn for this project as I have yarn in my stash that’s been sitting there for far too long. A granny square project like this is ideal for using up leftover yarn.
As luck would have it, I had enough yarn in lots of bright colours. Some I definitely ran out of and had to eke it out very carefully, but it is definitely the ultimate kind of Stash Busting. It felt so good to use it. It’s not all Paintbox DK cotton, but most of it probably is.
My advice for a crochet project like this is to make conscious choices about saving longer scraps of yarn for later granny square rounds. I used my tiniest yarn leftovers to work the first rounds. The amount I had of each colour definitely dictated colour choices; beyond that, I didn’t think about it too much.

Granny Bag Measurements and Useful Info
OK, we’re beginning to lay out a recipe here. I’ll start with measurements of the different bag elements.
One four-round granny square using my own pattern measures 12 cm across the diagonal.
The finished bag measures: 36 cm deep x 49 cm across (not including the handles or tabs).
You will need 42 granny squares and 12 granny triangles. I have video tutorials on how to crochet both – see links below.
Things You Need To Crochet A Granny Square Bag
- You need more than 352 grams of cotton DK yarn! This is what my bag weighed before its lining and handles. And you’d have to be very blessed to have the exact amounts in all the colours, so make sure you have more than that in total. You’ll need surplus to ensure you can do some jiggery pokery with colour combinations, etc. See below for a suggested palette.
- You will also need a 3.5mm crochet hook (we don’t want loose and floppy grannies, do we?!).
- Bag handles are from Amazon, Etsy, or a craft shop. Type “long bag handles” into Google, and these are bound to come up. They’re fairly common.
- Fabric for lining. Nothing fancy is needed; mine is probably cheap polycotton.
- Optional but advisable – a (working) sewing machine.
- Lots of bulb stitch markers, needle and thread.

Yarn Colours For Mum’s Granny Square Bag
I’ve mentioned yarn scraps and using yarn leftovers, and look, this is not a project where I can be precise with each colour. I can give you a rough idea of the colours, but they’re not all exact, as I actually used some other brands. However, assuming you want all the same, let’s go with Paintbox DK cotton, since that’s the majority. The shades are as follows (I’ve matched them as closely as possible where it’s a different brand).
If you had one ball in each colour, you would absolutely have enough to make Mum’s Granny Square Bag.
List of Colours Used:
- Spearmint
- Bubblegum Pink
- Vanilla Cream
- Slate Grey
- Lime Green
- Washed Teal
- Marine Blue
- Lapis Blue
- Pale Lilac
- Pansy Purple
- Raspberry
- Rose Red
- Daffodil Yellow
- Blood Orange
- Rosy Pink
- Coffee Bean

A Chart For Mum’s Granny Square Bag
This is so useful!! You’ll need this chart for the granny square layout.
I am embarrassed to admit that I got the shaping wrong twice before this successful attempt. My poor little noggin isn’t the sharpest at the moment, and I messed up. First, because I kept thinking I was going to be joining totally different square sides. After much confusion, I cut out a chart and folded it like a little origami piece. That way, I could actually see where each square needed to be joined. Oh dear!
Then, I completed a whole piece of fabric, had it bag-shaped and ready to line. It was enormous! I’d even sewn in all my ends. There were hours of unpicking to get rid of the extra granny squares I didn’t need. Arghh. Never mind, it’s a lesson in patience.
Right, let’s look at the (correct) chart below. The squares marked with asterisks indicate which to leave until all the others have been joined. You need to leave those to the end because they are the ones that turn a flat piece of fabric magically into a bag pocket – by the power of Join As You Go. Speaking of which…

Join As You Go Granny Squares
For a project like this, Join As You Go, or JAYG, is the best joining method for granny squares in my humble opinion. Well, you can sew them if you want to, but this is a heck of a lot quicker!
I have a tutorial for how to crochet granny squares with their petal centre. In the same video, I demonstrate a clear way of JAYG. And the written crochet pattern is here.
Work most of the squares in a flat piece of fabric. It’s only the last four squares that are joined on every side to turn the flat fabric into a 3-dimensional bag. Follow the chart, but also bear in mind that you might wish for an even distribution of colours.
Below is a photo of how I choose to distribute colours evenly. I absolutely played about a bit, switched around colours whenever I fancied. You do not have to be rigid in this kind of crochet project, and you can do what you like.
The photo might be one of the first attempts, so if you’re trying to copy, note that it could be wrong. However, it does a good job of showing, visually, what I mean by the distribution of colours.
I like the idea of having half a plan so that there’s freedom to make small adjustments should I decide that, actually, it’d be nice to make the final round a shade of green for a particular square rather than turquoise… Or, one section has the lion’s share of red; let’s spread it out a bit. Perhaps, it’s a bit like yarn ball chess! Sort of.

JAYG Granny Triangles
These form the bag top and side openings. I have a video tutorial for the granny triangle pattern. Here’s the link for how to crochet granny triangles.
I tweaked the hypotenuse of the triangle for the final round to remove a cluster (you’ll see in the video). The idea behind this was to get rid of any bulk at the tops of the bag. You don’t have to, though, and I’m not convinced my tweakings were worth it.
You use the same JAYG method for triangles as you do for squares.

Simple Tabs For The Granny Bag Opening
Once you’ve completed the joining of the granny squares, the bag needs a couple of tabs at the bag openings. These are to slide through the gaps in the handles, thus anchoring them in place once they’ve been stitched down.
The tabs consist of two rows of US double (UK treble) stitches followed by a final row of SC (UK dc) stitches to both opening ends. These tabs prevent the handles from gobbling up the granny triangles. I want to see my granny triangles in all their glory!
There is nothing fancy about these tabs; they’re for practical purposes only. Join in your preferred way and, for Row 1, crochet along the series of triangles. I didn’t take a photo, but you can see it more clearly in the Granny Square Bag video.

Sewing A Crochet Bag Lining
Once you’ve made Mum’s Granny Square Bag, make a simple lining. It really will add structural integrity and make your bag last longer. Everything I’ve done to sew this bag lining has been eyeballed.
Lay the crochet bag on top of a folded piece of complementary fabric that’s slightly larger than the crochet – something like a medium-weight cotton or polycotton is fine.
Mark where you’ll need to sew the side seam, where to stop and press the side openings, and where you’ll need to top stitch the opening hems. Once stitched and pressed, I placed the pocketty lining into the bag and pinned it in place so I could hand-stitch it securely.
If you’ve seen the video, you’ll know that I did not have a good time with the sewing machine. It’s almost entirely user error! Yet, despite my tantrums, I think you’ll get the gist.
Attaching Bag Handles to Crochet Fabric
Attaching bag handles doesn’t have to be perfectly done. I wriggle the top tabs through the handles and then pin them in place using lots of bulb stitch markers. When sewing the tabs down, I used doubled up thread. I think this makes it much more sturdy.

Another Granny’s Patchwork Bag. Future Plans!
So, what I’ve shared above isn’t the final iteration of Mum’s granny square bag. It’s not quite right yet. But don’t get me wrong, it’s a stunner, but I can make one that’s even better.
Mine is a different ratio than Mum’s patchwork bag, so I want to change that. Mine is a lot deeper, and I know what I’ll do to change it for next time. Basically, there are two main things to change: I can make the squares a round smaller, and increase the width of the fabric by adding another row of granny squares. That would adjust the proportions. Although don’t take my word for it just yet, I haven’t done my sums!
Then, I might use 4-ply yarn and keep the same number of rounds as this colourful version, but still add another row of squares. 4-ply cotton will make a smaller, lighter bag and remove any hint of bulk. Not that I think DK yarn is bulky, but eh, it is just a teensy bit. It makes it a heavier bag than I’d like, so I will need to go yarn shopping for 4-ply cotton – such a shame!
And when I do that, I will try to replicate the colour palette on Mum’s OG bag: lots of dusky hues and perhaps colour block squares rather than stash busting. What do you think?
