Why would a person trainer's time be worth $25 and hour and yours only $10? If you want that deal, that's up to you, but don't give yourself the sort end of the stick,and under value yourself. You don't have to look far on this board to find quilters who have made quilts for far less than they should have because they feel like they are charging too much, and regret having agreed to the project. In the end, it's your decision, but if you decide your time and skills are worth a decent going rate - at least as much as the personal trainer- you will have a whole lots of quilters who will back you up!!
