I'm not sure I understand your second question, but if you're asking about the actual cutting of pattern pieces, I vectored the pattern and use a laser cutter to cut out everything. 8D

Hmm, I'm not at all sure how to explain the leg thing...I'm terrible at putting sewing actions into writing >_> Basically I make sure that they match at the bottoms and then pin toward the middle from both sides (if that makes any sense @_@)
