Whoa! Read your second post, Bama, and it looks like you are really crowded. I'm jealous! I'm equally crowded but I don't have all the cool equipment you do!
My advice is - if it works and you might use it someday andyou have room for it, keep it! If you'll never need to buy one again and you don't use it, dispose of it.
But for heaven's sake keep your stash - and like the other poster said, be sure to stroke it before you fold it and put away.
That said...I generally don't buy misc random stuff (except for shoes!), and I don't dispose of anything I have bought unless it is broken and can't be economically fixed. Toaster and hair drier breakdowns are big on my hitlist of breaks-every-two-years products which I hate. I am still wearing a gorgeous pair of leather boots bought at Marshalls/TJ's maybe 25 years ago and I get compliments, and all they need is soles, heels, and occasional stitch, and polish. When clothes leave my house they go to a recycling bin because they are not 'gently worn' LOL, unless they shrunk! I have kept gowns and outfits I love even if I never weigh 90LB again because...uh-oh! Because!
