Have you discovered Shadow knitting yet? It’s a lot of fun and makes for some interesting discussions with folks who see your project.
When viewed from the “normal” straight down angle, your knitting looks like a colorful ribbing project. You can use any colors you wish, but contrasting colors work best. Alternating colors every 2 rows.
Found this great little book called Shadow Knitting by Vivian Hoxbro. The book contains very nice detailed patterns for winged shawls, squared bags, a matching cap and scarf, vests, sweaters, and Japanese-style kimonos. $14.93 on Amazon.
