Marcy J. I like your question.
I am in my early 60 and I was thinking like that ever since I started to quilt and that is only 4 or 5 years ago. I kept having projects and I could not believe how much different fabrics I either "needed" to buy for a project or wanted to buy because I thought it was perfect with the fabrics I already had.
Then, I started thinking that I should finish one project before starting to buy for another one, so that I would not leave too much UFOs behind me for those who would have to get rid of my stuff after I'm gone.
that thought changed totally when I mentioned that to my SIL (my husband's sister)who is a quilter and she spontaneously said to me, "don't worry about it, I'll gladly take all your stuff with me" and she is 15 years younger that me..
Since then.... I don't worry about it as I think I will make her so happy and that thought makes me happy.
Before, I kept saying to myself that it would be a bother for everyone. I only have a brother, and his wife and 3 daughters are not at all interested into crafs or quilt. I did not want to make quilts for "nobody" who would not appreciate them. and I had forgotten my husband's sister thinking she had more fabrics than I would ever have...
The fact that she wants it makes me buy fabrics because I like it now, and with no projects in mind. It is worth money and will probably be even more appreciated!
just live now! and find a group that will love to have your "leftovers"
