I'm grabbing every favourite piece of clothing I have around the house and mending it with a needle and thread
I'm not very good at it, but it's not terribly hard to close up broken seams good enough for some use. It sure as heck beats buying a new pair of jeans for $70 just because I somehow destroy the crotch every year
I'm finding this to be really satisfying and relatively easy to do. Certainly I can develop better stitching technique and use better tools and material, but it's easy enough to be good enough, or so it seems to me now
I don't know much about quilting, but I wouldn't want to miss my serger (got a cheap one from Lidl 3 or 4 years ago)
Fininhing edges when shortening trousers, or quickly taking in a shirt in one go... I love it. Yes, definitely worth it!
