Bearpaws, that is such a loaded question. Everytime I finish a new project, it's like I've given birth to a new child & just cannot part with it. If I have somebody in mind for it in the beginning, I can let it go. Otherwise, it goes on the pile & I rotate everything. Tablerunners, wallhangings, & quilts.
I used to have a neighbor who lived fulltime in a lg. motorhome. All she did was quilt. You could not sit anywhere in her rig without having to move piles of quilt TOPS. That's all she did. Never finished any of them. I hope a quilter inherits her stuff when she passes away someday.
I, too, enjoy the planning & fabrics. Just enjoy what you love & don't worry about the rest. Or pass on your tops to somebody who wants to finish them. Just a thought. Pat
