I like trying new gadgets out but I don't need to keep them if they don't rock my world so I don't hang onto them like I hang onto fabric. I've accumulated a few "students" - four ladies from work who are new sewers, and they've been wonderful for passing on gadgets I don't like or don't use. They come over and we have a sewing day, and I pass out things I don't want anymore and tell them, "Try this, if you like it, it's yours." I've gotten rid of all sorts of doo-dads that way!
Of course, for Christmas, I had to put together "goodie" bags for each of them with duplicates of some of my favorite tools that I'll never part with! That was fun.
