About the diamond granny square.

This pattern is called the diamond granny square because no matter which way you keep turning it, you’ll see a diamond. It’s also referred to as the square in a square for the same reason; whichever way you turn it, you find a square.

For this pattern, I stopped the diamond effect after 3 rounds. However, you can continue with the same pattern repeat to get 4, 5 and even more diamond.

Notes:

  • Read through the pattern before starting your work just to be sure you don’t have any questions that might cause frustration while working on the project.
  • This pattern is written in US terms. For a conversion into UK terms, get my free eBook with the conversion charts here.
  • The pattern is worked in joined rounds.
  • Repeating sections within the rounds are shown in round () brackets followed by the number of times they are repeated e.g. (Dc in next st, 2 dc in next st11 times means the sequence in the brackets must be repeated a total of 11 times.
  • Stitch totals are shown in square [] brackets at the end of each round e.g. [12] means you should have a total of 12 stitches at the end of the round.

Instructions:

Using C1 and 4 mm crochet hook, ch 4. Join with a sl st to the first ch to form a ring.

.

Rnd 1: Ch 3 (counts as first dc), 2 dc into the ring. (ch 3, 3 dc into the ring) 3 times. Ch 3. Sl st to the top of starting ch 3. Fasten off C1 [9 dc & 4 ch-2 spaces]

Round 1

Rnd 2: For this round, we’re going to start working from the chain spaces created in round 1.

  • First, join C2 in any ch-2 space and ch 1 (counts as 1 sc).
  • Secondly, work (3 dc, ch 2, 3 dc) in the middle dc of the first 3-dc cluster.
  • Thirdly, (Sc in the next ch-2 space. (3 dc, ch 2, 3 dc) in the middle dc of the next 3-dc cluster). The pattern indicated in the bold brackets ( ) is what we’ll be repeating for this round.
  • So, repeat the pattern as indicated in the bold brackets ( ). Join with a slip stitch to the first chain.  Fasten off C2. [24 dc, 4 sc and 4 ch-2 spaces]
Turn your square 45 degrees and work as shown

Rnd 3: Just like in round 2, we’re going to be working in the chain spaces created in the previous round. Not only that, we’ll also be working in the middle stitches on the edges, which are the single crochet stitches this time round.

  • So, first off, we’ll join C3 in any ch-2 space and ch 2 (counts as 1 sc and ch-1 sp).
  • From there, work (3 dc, ch 2, 3 dc) in the sc; the middle stitch we had talked about earlier.
  • Thirdly, (ch 1, Sc in the next ch-2 space. (3 dc, ch 2, 3 dc) in the next sc). The pattern indicated in the bold brackets ( ) is what we’ll be repeating for this round.
  • So, repeat the pattern as indicated in the bold brackets ( ). Join with a slip stitch to the first chain.  Fasten off C3. [24 dc, 4 sc, 8 ch-1 spaces and 4 ch-2 spaces]

Rnd 4: For this round, we’ll be working dc in every stitch across with (3dc, ch 2, 3 dc) in every corner space. [60 dc and 4 ch-2 spaces]

Round 4

I like getting all my dc stitches stacked up nicely. For the same effect, once you get to the ch-1 spaces, instead of working into the space, work your dc under the front and back loops as shown with the red darning needle below.

Rnd 6: Worked similar to round 5. However instead of 3 dcs for the corner spaces, you’ll work 2 dcs. In other words dc in every stitch across with (2 dc, ch 2, 2 dc) in every corner space. [68 dc and 4 ch-2 spaces]
