I've nearly finished a patchwork blanket for my nearly 4 month old son, the colors are pastels. Blue, Green, Yellow, and White, heres the trouble. I've used these colors to make 12 x 12 squares (similar to tenstion squares) in each color, I intend to place these squares so that no color touches another kind of a patchwork style. Here is the trouble, what color do I use to whip stitch all these squares together with? So far (I've only finished the blue and green squares) I've got 5 squares of each color. So knowing that I don't want any same color to touch does anyone have any suggestions. The type of yarn is Lion Brand Yarn Velvet Spun. Thanks.
