Josiah's Blankie

I got part of Josiah's blankie done. I made 3 of the rings of part of the squares. I think i'm going to crochet 6 of each 3 colors, depending on how big it's going to be. They are 6 inch blocks. This is the pattern i'm using - http://mannerscrochetandcraft.blogspot.com/2009/03/circle-in-square-block.html . It's pretty simple so far. Anyway, here is a photo of the first ring i made.
