September Granny Square

A crocheted square featuring a central apple design, surrounded by colorful building blocks with letters 'A', 'B', 'C' and numbers '1', '2', '3'. The square has a black border and green background, symbolizing a back-to-school theme.

Hello and welcome to Part 9 of the Making Stitches 2025 CAL!

In my world, at least for the next few years, September means ‘back to school’ and while it’s been a long time since anyone in our house was learning their abcs, I thought it would be fun to revisit those early years of Primary school with an ‘A for apple’ inspired square for September’s Making Stitches 2025 CAL square.

This fun square has an apple at its heart, and it’s surrounded by a blackboard inspired black border (sorry for anyone who hates crocheting with black yarn or anyone who is too young to remember blackboards in school!) and some alphabet and number building blocks.

The whole point of this CAL is to be a stash buster project to help you get rid of some of your odds and ends of yarn left over from previous projects. I am certainly using it for that purpose!

I have made my squares using my own stash of Stylecraft Special DK yarns and I have included the names and numbers of the shades I’ve used in case you want to replicate what I have done exactly, but you can use any yarn you like. The only thing you need to do is make sure it’s all the same weight, ie all DK or all Aran or whatever yarn you choose, and if you are making the whole project along with me, make sure all your squares are made using the same weight and the same size of crochet hook to make sure they all measure the same size so they can be joined together easily at the end.

Here’s the pattern for my September Making Stitches 2025 CAL square!

Round 4 Work in the blo in this round With Yarn B, make 3 fptr around the ch3 of Round 2. Then count up to the 13th st of Round 2 and mark it with a stitch marker – this is where the next group of fptr sts will be worked. [Miss the next 2 sts, 1dc in next st, (2dc in next st, 1dc in next 2 sts) 5 times] make 3 fptr around the st marked with the marker, then repeat the section in [brackets]. Slst into top of ch1. Fasten off and break yarn. (48dc)

Round 5 Work into the blo of this round Join Yarn c into the central st of one of the 3fptr groups. Ch1, (2dc in next st, 1dc in next 3 sts) rep around. (60 dc)

Round 6 With Yarn D ch1, 1dc in next 3 sts, 1htr in next 2 sts, 1tr in next 2 sts, 1dtr + 2ch + 1dtr in next st, 1tr in next 2 sts, 1htr in next 2 sts, 1dc in next 6 sts, 1htr in next 2 sts, 1tr in next 2 sts, 1dtr + 2ch + 1dtr in next st, 1tr in next 2 sts, 1htr in next 2 sts, 1dc in next 3 sts changing to Yarn B in fyo of 3rd st, with Yarn B 1dc in next 3 sts, 1htr in next 2 sts, 1tr in next 2 sts, 1dtr + 2ch + 1dtr in next st, 1tr in next 2 sts, 1htr in next 2 sts, 1dc in next 6 sts, 1htr in next 2 sts, 1tr in next 2 sts, 1dtr + 2ch + 1dtr in next st, 1tr in next 2 sts, 1htr in next 2 st, 1dc in next 3 sts slst into top of ch1 to close round. Fasten off and break yarn. You now have your main square. (64 sts)

At this point, it is time to make your building blocks – you will need 6 in total, 2 in red, 2 in blue and 2 in yellow.

To make a building block:

Using Yarn B, E & F make six blocks.

Row 1 Ch5, 1dc in 2nd ch from hook and back along the chain, turn. (4dc)

Row 2 Ch1, 1dc in next 4 sts, turn. (4dc)

Rows 3 & 4 Rep Row 2. At the end of Row 4, make 2 dc in final st to turn the corner, turn square 90 degrees, work along the side of the square working 1dc into every row end, work 2dc into the corner, turn square 90 degrees, 1dc into each of the foundation chains along the bottom of the square, then turn the corner again and work back up the other side. Slst into the first st of Row 4. Fasten off and break yarn, weave in your ends.

Once you have 6 building blocks made, embroider them in chain st using Yarn D with A,B,C,1,2 & 3.

To make the border:

Border Round 1 Work in the blo in this round. Join Yarn D into any st on one of the sides of the main square (not the top or the bottom). Work 1dc into every st around and 1dc ch2 1dc into every corner space. Slst to top of 1ch. (72dc)

Border Round 2 ch2 & 1htr in every st to the corner, in corner space work 1htr + 2ch + 1htr, then 1htr in the next st.m Take the first building block you need to join (as I started the round on the right hand side of the square, in the case of the picture below it is ‘C’) hold the building block and the main square right sides together and join the building block to the main square working into the blo of the building block’s bottom edge and 1htr into the next st on the main square joining both together. Work 1htr through the remaining sts along the edge of the building block and through the next 3 sts of the main square. Then work 1htr into the next 2 sts on the main square before repeating the join with the next building block (block ‘B’ below), once you have worked 1htr into each of the 4 sts along the base of that block, work 1htr into the next 2 sts and join the next block (block ‘A’ below) the same way, work 1htr in the final st on the main square, 1htr + 2ch + 1htr into the corner space, work 1htr in every st along the side of the main square and repeat the process of joining the blocks (1,2 & 3 below) along the bottom of the main square. Work 1htr + 2ch + 1htr in the corner and 1htr into the remaining unworked sts up the side to the beginning of the round. Slst into the top of the ch2 to close the round. (80 htr)

Border Round 3 Ch2, 1htr in every st around. 1htr + 2ch + 1htr in the corner spaces. Slst into the top of the ch2 to close the round. (22 sts on each side = 88 sts in round)

Border Round 4 Rep Border Round 3 (24 sts on each side = 96 sts in round)

Border Round 5 Rep Border Round 3 (26 sts on each side = 104 sts in round)

Border Round 6 Rep Border Round 3 (28 sts on each side = 112 sts in round)

Border Round 7 Ch1 1dc in every st around, 1dc + 2ch + 1dc in the corner spaces. However, when you reach the top of each of the building blocks, join the top edge by working your dc through the blo of the building block and the border row behind it. Work 1dc into the top of each 4 st along the top of each block and 1dc into the next 2 sts to keep the blocks straight and to mirror what you did in the joining row of Border Row 2. At the end of the round, slst into the top of the ch1, fasten off and break yarn. (30 sts on each side = 120 sts in round).

Then, with yarn C, you can surface crochet around the sts in Border Round 7 to give a green stripe around the edge of the square. When you get to the corner spaces, slst around the corner edge to keep the green embellishment nice and square. Note: be careful not to make your surface crochet too tight, so the square doesn’t get pulled out of shape.

So there you have it, your Making Stitches 2025 CAL September Back to School square is completed. I hope you enjoy making one, or maybe even more than one!

I would like to say a huge thank you to everyone who joined in with the CAL during August – it was a two square month with the Seaside Holiday Square and the Bonus Granny Square Day Square. It was so lovely to see them appearing on Instagram over the last few weeks! In particular, thanks to Annette from @etenamakes, Kristina from @crochet_at_holme, Judith from @judithlouise21 & Sarah from @sarahsheehangib – you can see their squares here.

Whether you are caught up in the ‘back to school’ chaos or not, I hope September is a good month for you.

Happy hooking!
