Years ago, I offered to make an over-size queen quilt for a friend when she re-painted her bedroom. I was envisioning using up a lot of blue and cream fabric I already had. Turns out she didn't like some of the fabrics and I ended up spending money on more fabric. (It didn't seem right to expect her to buy the fabric since I offered to make her the quilt.). So it kind of turned into an expensive obligation. While I was making the quilt, I felt like I can't wait to get done with this.
Last year I had so much fun making a wallhanging size quilted backround and then quick FMQ circles on top of it. I actually thought of asking all of my FaceBook friends if anyone wanted me to make one for them! Then I thought NO because people would say they wanted certain colors or sizes. And I'd be sorry I offered!
Now I do make quilts for people, but they don't usually know they're the lucky recipient until I give it to them. For me, feeling obligated takes the fun out of doing it.
