Instructions
Make the Center Circle
Crochet Hook Size I 5.5mm
Start by making a slip knot and adding the loop on the hook. For the crochet tutorial today, I used the chain stitch method.
75 yards Yarn.
Chain 4, Slip Stitch back into the first chain to close the circle and make a ring.
Round 1
This round and each round start with a partial puff stitch. Also, for round 1, you will be working your stitches inside the circle.
CH 2 (counts toward your first puff stitch). Now you need to work 2 more stitches. Work a partial puff stitch. Yarn over insert your hook in the circle and pull up a loop and then yarn over insert the hook and pull up a loop. At this point, you should have 5 loops on your hook. Yarn over and pull through all five loops. Finish with a chain one to close the puff stitch.
Since we are starting with 8 puff stitches for round 1. We need to make 7 more puff stitches.
Yarn over, insert the hook in the circle. Yarn over again and pull up a loop. This is the first stitch. Yarn over, insert the hook in the circle, yarn over and pull up a loop. This is the second stitch and there should be five loops on your hook. Let’s work the last stitch. Yarn over, insert the hook in the circle, yarn over and pull up a loop. Now there should be seven loops on your hook. Now close it up by completing a chain one.
Repeat the PS 6 more times.
At this point, you should have a total of 8 puff stitches complete. Let’s close round 1. Slip stitch into the top of the first puff.
Round 2
In this round, you will double the number of puffs.
SL ST into the first chain space between the puffs.
Begin with the partial puff stitch. In the same SP, work full PS.
Insert your hook in the next stitch, which is the Cain Stitch Space and work a complete PS. Chain to finish. In the same SP work another complete PS. CH ST to finish.
Continue moving around to each SP working 2 PS in each SP. When you have 16 STs completed, close round 2 by SL ST to the top ST of the first puff.
Round 3
In this round you will add 8 more puffs. We keep the circle flat by adding the extra puff every other space.
Work a partial PS. In the same SP work another PS. Move to the next SP and work 1 PS. [In the next SP work 2 PS, in the next SP work 1 PS]. Repeat between [ ] until you have completed 24 Puff STs in this round. Close round 3 by SL ST to the top ST of the first puff.
Round 4
Using smaller crochet hook Size H 5.0mm
Change Color. Join yarn between any two puff stitches.
CH 3 (Counts as DC). 2 DC in the same SP. 3 DC in each SP around the circle. SL ST into the top of the beginning CH ST to Join. (24, 3 DC clusters)
Round 5
In this round we are creating corners.
Note. The stitches in this round and round 6 are worked between the clusters of stitches from the previous round.
SL ST into the next SP between the 3 DC clusters, CH 1. (Does Not count as a ST). 3 SC in the same SP, 3 HDC in the next SP, 3 DC in the next SP. Work (3 TR, CH 1, 3 TR) in the next SP. (First corner). [3 DC in the next SP, 3 HDC in the next SP, 3 SC in the next SP, 3 HDC in the next SP, 3 DC in the next SP ((3 TR, CH 1, 3 TR) in the next SP]. (Second corner). Repeat between [ ] around two more times. Then finish the first side by working 3 DC in the next SP, 3 HDC in the next SP, SL ST into the first SC ST to join. (There should be 4 corners complete and 28 clusters of STs total).
Variation. in the corner SP you can also work a CH 2 or CH 3 rather than the CH 1 depending on the size of the hole you desire for the corners.
Round 6
SL ST into the next SP between the clusters. CH 3, 2 DC in the same SP. [Work 3 DC in each SP between the clusters to the corner. In the corner work (3 DC, CH 1, 3 DC)]. Repeat between [ ] around three more times. End with a SL ST to the top CH of the first CH STs to join. (There should be 32 clusters of STs total).
Rounds 7 and Beyond
If you wish to make the square larger, you can continue adding rounds to the square using the instructions for round 6. The rounds on each side will increase by 1 cluster with each round complete.
Finishing
Cut off a long tail about 10-12 inches. Pull the yarn through the last stitch. Use the tapestry needle to weave the yarn back and forth through the crochet stitches. At least 4 or 5 times. Cut off any excess yarn.
