337-344::365 popcorn & cluster flower squares

Pattern: experiment in using different numbers of popcorn & cluster stitches.

This is sort of a continuation of my circle-to-square series. I began with a two round circle made with centers of 4, 5, 6, or 7 popcorn or cluster stitches separated by 3 chain stitches. The second round of each was made with two stitches in each chain space also separated by 3 chain stitches. The ones with an even number of center stitches were pretty easy to transform into squares, but the odd numbered ones were kind of tricky. With a little math and trail and error, it wasn't impossible. For the odd ones I worked a round of single crochet in white, making sure that the number of stitches all the way around was divisible by four so the corners could be evenly spaced. Then I used the next round to square it up.
