Came across this pattern on Ravelry recently. It's a practice square for the 2011 Block-A-Month (BAM) Crochet-Along (CAL) group.
I think I may use it to create a new baby blanket for our church nursery. Only problem is that I'll need like 20 or 30 little squares depending on how big or small I want the blanket. Wow that's a lot of squares. I don't know what is harder - 30 squares or making one by just making increasing rounds like here or here
