Hi, BW,
My parents were young adults during the Depression, and all their thrifty ways are second nature to me. I was dollar-stretching even when my husband & I were well off.
But now I'm slowly letting go of some of that. For example, I use bobby pins, and you know how the rubber tips get loose and snag your hair? I'm at the age where every strand of hair counts, so I started throwing out the snaggy pins.
Also I decided that when I buy a 6-pack of panties, I get to throw away the 6 worst, most elastic-challenged old ones, and not keep them for that (let's face it) mythical day when I'll put in new elastic. Bonus: I get to reclaim 6 safety pins for other uses.
About those future sewing projects: when I moved here there were cartons and bags of holey socks, torn jeans, etc. My husband wore those steel-toed workboots and would get one wearing out of a pair of socks, so I was forever darning or resewing or patching socks by cannibalizing other, holier socks. it was sort of fun, actually. Now that's not necessary but I'm thinking, "well, I could make potholders out of this material." But how many potholders can a person use? Like so many of us, I have only 2 hands. So I'm slowly letting go of some of this old stuff.
Your posting makes a good point - we all draw our "stretchy" lines in different places. Whatever makes sense to you, you should do. Or not do. Whatever.

P.S. Living alone, I'm missing rescuing detergent and shampoo bottles from laundry room and Dumpster, setting them up the bathtub to drain out, swishing the last little bit out with water. Great stretching! Do any of the rest of you routinely add water to your shampoo and dish detergent? It works well if you give the bottle a shake every time, and rinses out more efficiently.
