I don't feel obligated at all. In fact, I find it kind of annoying when people see the bags or quilt tops I have made and ask if/when I could make one for then, expecting that it will be free, and when I mention that materials and my time cost, some have actually said they wouldn't expect me to charge them. Now I am always speechless, even though it has happened several times. So, when I recover I just repeat that this is an expensive and time consuming hobby of mine and I can't support them as well, but I could let them know my prices and they can decide for themselves. IMHO, they don't seem to understand the work involved, as well as the money, and they probably wouldn't even appreciate it so don't let it bother you. :D
