I know many of you don't have babies and don't have a need for a sling but IF you did---and you were interested in buying one like this...how much do you think you would be willing to pay? I made this one and I have an acquaintance that is interested in purchasing one from me. I'm having a hard time with a price. I want to charge enough that I'm not doing free labor but I don't want to charge so much that it seems unreasonable. Any opinions? Thanks a bunch!
