1. Be proud that your friend values your craft and asked for you to make a quilt for a special occasion.
2. Keep reminding yourself that this is not a quilt you will keep. Therefore, it doesn't matter if YOU like it or not. It matters that your friend (and her niece) like it.
3. Find something about it that you appreciate. (Color, pattern, your perfect 1/4" seam, the seams pressed correctly.....)
4. Set yourself mini-goals and work at one goal at a time. That way you don't think of "HAVING to finish a quilt" but finishing step X. It will be done before you know it.
Hope that helps. Yes, I have worked on quilts I don't like, so I had to suspend my emotions. I was always surprised by the end of the project how much I had grown to like it.
