I found this vest on Melody Johnson’s Fibermania blog. She said she made it from the book Dazzling Knits: Building Blocks to Creative Knitting by Patricia Werner (Martingale & Company, 2004).
I liked the idea of modular knitting – putting together blocks would be sort of like quilting. I sent for the book (and the T-shirt). The book arrived and I learned that double pointed needles are required to do the work. Double pointed needles! I have lots of regular bamboo needles, but no double pointed needles. Oh dear. Perhaps I’ll just knit something in rainbow colors.
