If this is new for you I would pass on a commission quilt. If this was an experiment quilt for you I would say go for it. I would also say go for it if you had done this type of quilt before. I have had my girls in dance and the leotards are not cheap and I have all kinds from basic to velvet to fancy. Because she's wanting to preserve them unless I was confident I would not take the responsibility of that first cut. What if she hates it? what if you get started and realize it's not possible and you've already cut one or two leos up....do you have to compensate far beyond what you think it's worth? I've found when things are commissioned some people forget that they are being made by a human and not a robot if that makes sense. That's why I'm chicken and don't quilt for anyone but me and gifts!! I wish you the best and I want to see it if you decide to take it on!!
