Pattern: "E-2" from Better Homes and Gardens Crocheting and Knitting "Granny Square Sampler Afghan."
I had a couple of issues with this square. In the picture in the book, round 3 (the one with the clusters of 2dc) is much more circular. Though the pattern doesn't specify, I think that they crocheted into the back loop only of the previous round. There are a couple more of these squares in the afghan, so I'll try that next time. The very last round was supposed to be spaced with 2 stitches between each "shell," but again the square was way too wavy that way, so instead I alternated with 3dc and 2dc between each. Now it is actually square and not roundish-with-points! This square is 6".
