For the curious knitters, the pattern is the Garter Stitch Blanket from Baby Knits for Beginners by Debbie Bliss. I used Rowan Handknit DK Cotton yarn in 203 (pink), 239 (blue), 253 (taupe), 301 (green) and 334 (purple). Some of those colors have been discontinued but may still be available on yarn store shelves or online. The 72 squares, all in garter stitch, knit up super fast on a pair of size 8 Addy Turbos, but the piecing together took a while.
I hope the baby takes to this better than Aldus took to the Big Bad Baby Blanket.
