A few subtle changes in the center of this square can make a dramatic impact: swap out your double crochets for triples, and work clusters of two instead of three.

What You Need
Pro Tip: You can use any yarn and hook to make these squares, just remember that the weight of your yarn and size of your hook will change the finished size of your square.
Chain 6 (counts as first tr and ch 2).
Work all of the following sts in the 6th ch from the hook:
(Tr, ch 2) 7 times.
Join new color of yarn in any ch-2 space.
Working in same space: Ch 3, 2 dc, ch 2, 3 dc to create first corner.
[Ch 1, sk next ch-2 space, (3 dc, ch 2, 3 dc) in next ch-2 space] 3 times, ch 1, sl st to top of ch 3 to close round.
If you’re done with this color, fasten off and weave in ends. Or, work another round with this color, like we did.
Round 3 and Beyond
From here on out, you’re working traditional granny rounds. Follow the instructions below, just adding an additional ch 1, 3 dc between each corner as you add more rounds.
Join new color of yarn in any ch-3 corner space from Round 2 (or, if you’re sticking with the same color as the previous round, sl st to the next ch-3 corner space).
Working in that same space: ch 3, 2 dc, ch 3, 3 dc (first corner made), [(ch 1, 3 dc) in next ch-3 sp, (ch 1, 3 dc, ch 3, 3 dc) in next ch-3 sp] 3 times, (ch 1, 3 dc) in next ch-3 sp, ch 1, sl st to top of first ch-3 to close round.
