How to Make a Half Granny Square, Step-by-Step Instructions
Style 1 - Easy Half Granny Square Crochet Pattern
Here are the instructions for a half granny square with holes.
Row 1:
- Make a magic ring (this counts as a dc and a ch-1 space). If you don't like using the magic ring, you can ch 5, then slip stitch into the first chain to make a ring.
- Work 4 ch, 3 dc, 2 ch, 3 dc, 1 ch, and 1 dc into the ring.
- Pull the magic ring tight if you used one.
If you are making a multicolored half granny square you may join a new yarn color on every subsequent round.
Row 2:
- Chain 4 (this counts as a dc and a ch-1 space) and turn your work.
- In the first chain-1 space, [dc 3], then chain 1.
- [dc 3, ch 2, dc 3] in the next ch-2 space.
- [dc 3] in the last ch space.
- Ch 1, and dc in the third ch from row 1's first four ch. (Do not skip this last ch and dc, you may think is is unnecessary, but it gives the triangle a nice straight edge.)
Row 3:
- Chain 4 (this counts as a double crochet and a chain-1 space) and turn.
- [Dc 3, ch 1] in each ch-1 space on the first side,
- [dc 3, ch 2, dc 3] in the ch-2 sp at the triangle's point,
- [ch 1, dc 3] in each ch-1 space on the second side.
- Ch 1, dc 1 in the last stitch (the third ch made from the first four ch made in the previous row).
Finishing:
- Repeat row 3 until your triangle is the size you require. The number of rounds is up to you.
- Cut yarn, fasten off, and weave ends in. If you used multiple colors instead of the solid color in this sample, you will have a lot of ends to weave.
Style 2 - Solid Granny Style
Here is how to make a half granny square that is solid. Read about how to make solid granny squares.
Row 1:
- Make a magic ring and chain 4 (this counts as a dc and a ch-1 space). If you don't like using the magic ring, you can ch 5, then slip stitch into the first chain to make a ring.
- Chain 3 (this and all future rounds count as 1 dc),
- 4 dc in ring, chain 2, 5 dc in ring. (You have 2 dc clusters and 1 ch2 space)
Row 2:
- Ch3, turn work,
- 2 dc in the first stitch, 1 dc in each of the next 4 stitches,
- 2 dc, ch2, 2 dc in the ch2 corner space to make a corner,
- 1 dc in each of the next 4 stitches, and 3 dc in the last stitch.
Row 3:
- Chain 3, turn work, 2 dc in the first stitch,
- 1 dc in each of the next 8 stitches,
- 2 dc, chain 2, 2 dc in the ch2 corner space to make the point of the triangle,
- 1 dc in each of the next 8 stitches,
- 3 dc in the last stitch.
Finishing:
- Repeat row 3, increasing your dc stitches in each row until your triangle is the size you require.
- Cut yarn, fasten off, and weave ends in.
Half Granny Square FAQs
Is it a Half Granny Square Or a Granny Square Triangle?
Well, actually, both! It is triangular, and its shape corresponds to the diagonal that runs halfway across a traditional granny square. When crocheting a granny square blanket with the granny squares slanted on their tips (in a diamond shape), half granny square triangles come in handy.
In that scenario, you'll want to add these half-grannies to fill in the gaps at the border. In other words, if you rotate your Granny Squares so that the corners are on the top and bottom and left and right sides of your project, you will need to make half granny squares to fill in the gaps and make the edges straight.
