What are you most proud of? I really worked with the YO/decrease combos to get as much movement as possible in the trains. Although this means the knitter needs to pay a little more attention to the instructions, the end result give a motion feel. What advice would you give someone starting this project? As noted in the pattern, not all wrong side rows are just purls. Make sure you pay careful attention the first set of trains and then the rest is cake. Choo Choo!!!
