he buys the fabric (ie materials in total), you supply the labor (which is intensive), in my opinion, you take the cost (his expense), remove it, then figure your labor, i know what it is like to be undervalued, and broke, but you might find yourself working for fifty cents an hour if you are luck, if you look at the books "quilt in a day" log cabin for example, they take more than a day, look at what a good handmade quilt (handquilting) would really cost, i assume that is what you are planning, how many stitches to an inch? billions, i love the idea, but for other than art quilts i believe you will not be happy with the arrangement, do you have anyone in your area/family that can give you good legal advice, do not enter a contractual agreement without it, we all love to have our work admired, and appreciated, then sometimes a carrot dangles in front of us, and it is hard to get by on almost nothing, i wish you well
be careful, my instinct is to say yes to one, and test the waters, but nothing else, your pattern, your choice, and see how it goes, do not forget the time to wash (water/soap), to dry, to iron, to press the points (elec), and so on, plus all else goes into a fabric creation
