I know this is an age-old question but recently I was offered the opportunity to sew American Girl doll clothing for someone who remakes and rescues AG dolls. Her work is beautiful and I'd like to help her out as she suffers from severe health problems and really needs some help. She is not a close friend so it would be a business deal but HOW DO I DETERMINE FAIRLY what price to charge for my outfits? I mean really, how do I set the price--by hour, by cost of materials, by difficulty of pattern, etc. Any suggestions and pointers would be so appreciated by me. I also have another friend who is sewing for her and needs the same help. Thanks in advance.
