I have decided that I will have three rates for any quilts I might make.
1) Gifts of love and/or charity - I buy everything and donate the time
2) You buy the fabric and I donate the time
3) About $15 per square foot for an "easy" quilt and about $30 per square foot for something more complicated - plus the cost of materials. (I think that translates into - I don't really want to do commissioned/hired work)
