I forced myself to finish a king size quilt when I was bored with the pattern and just tired of working on it. Didn't want to waste the time and money I already had invested in it. I finished it, but it burnt me out on quilting for about 3 months. And I don't enjoy the finished quilt. When I look at it I remember the frustration I felt working on it. If it happens again, I will make the blocks already done into a smaller project such as a table runner, potholders, etc. and use the rest of the fabric in another project. I won't put myself through that frustration again.
