I like the idea of knitting one side at a time! Then I definitely wouldn't have to worry about increasing at the corners. Just afterwards seam the edges together, I really want that method to work versus knitting hundreds of stitches in the round!
Hopefully I get to start on this soon! I always start another project in the middle of one and I'm making myself finish the other 3 I've got going before starting this one. It helps that I don't have the yarn for it either
