What advice would you give someone starting this project? Not really an advice, but so you know... This is my second and third pair of booties I made (same pattern, different yarn and colors) The pink and white one is made with must smaller yarn, so I used the two color at once and I made the 6 to 12 months size one. I had to add some rows in the body part so it was the same height. The result with this size of yarn is a much smaller bootie, even if I used the 6 to 12 months pattern. It is the good size for a newborn baby. The multi-color one is a 0 to 6 month pattern with regular yarn.
