I feel ya'. I always make a quilt for my dog club's extravagant Christmas party gift exchange, and afterwards there's no shortage of people asking me if I make quilts on commission, and how much would I charge. I always say that this is my hobby only, and I can't take the pressure of "having" to do something! (However, if it's a friend doing the asking, I just might "happen" to have a quilt for them sooner or later. But no pressure!)
I don't even like being asked to fix up my own quilts when they're worn, though I have replaced a binding or two. But in general, it ruins it for me to have to do something on demand. Then it becomes work.
I really learned my lesson from a particularly bizarre situation. Get this, and tell me if I was crazy or not.
Made an online friend. We chatted a lot, visited the same places, wrote back and forth, just really got to know one another, became quite close as online friendships go. I was in a really hot quilting mode at the time, so I eventually told her I'd like to make her a wall hanging featuring her breed of dog, and asked her what colors she'd like.
She asked if I would make a wall hanging for a good friend of hers instead.
Huh?
Now, this was years ago, and I didn't have the spine then that I do now, but I tried to gently say that I wanted to make something for HER, my friend, not some (to me) random person. She countered that I would be making it "for her," in a way, and if I was offering to make her a quilt, then I should be willing to do what she asked. She'd even send me the fabric.
I wasn't very happy about it, but conceded. She did send me some very nice fabric, but became very demanding and picky about the whole thing, wanting to see pictures of the work in progress and critiquing it along the way. I did finish the piece (and it was very nice, if I do say so myself), but after receiving it and thanking me profusely (I'll give her that, she did appreciate it), the friend and I quickly lost touch, never to speak to one another again. I just never felt the same about her after that. I felt like I'd been taken advantage of, pressured up, used.
So now I have no problem whatsoever saying no to any sort of work on demand.
