This is thought provoking. I have also begun to think more this way. My quilt guild had an auction last week as a fund raiser. I had fabric I didn't like that was given to me that I always felt I needed to use. I felt like it was staring at me from my stash to be used. I use it mostly to make donation quilts. Since I don't really like the fabric I don't enjoy the projects. Other people love them. I took it all to the auctions and now it is all gone. Other people went nuts over it. I have plenty in my stash to make donation quilts I will enjoy working on more. Why should I use my precious time sewing something I don't enjoy.
Also I am makig a quilt for my GS who will be 2 soon. It is for his big boy bed. I had a layer cake ( don't usually buy pre cuts) that I really liked. I pulled it out to use and put it back because it was one of those fabrics that was too precious to cut up. As I dug for something else to use I thought " that was stupid" if my GS isn't precious enough for this fabric who is. It is working out perfectly.
Your time is precious. You will never get it back. What you want to do.
