This is based on Maggie Righetti's Dumb Baby Sweater, in the book Knitting in Plain English. I used a denim-y Canadiana and size 8 needles. I put a six-stitch rope cable down each sleeve to make it more interesting to knit. Since I had no time to go looking for buttons, I used Kathleen Day's I-cord knots as buttons. The different colors came because I had that many different colors of Canadiana on hand.
