Yessss! Just got a sewing machine and finished my first bag (it took me like two months on and off) and I'm never going to toss torn clothing again.
I ordered this cool graphic t-shirt and it was way too big, so I complained to the retailer and they sent a smaller one and told me to keep it. So I took a stab at taking it in, and, well, it went terribly (I need a walking foot for stretchy fabrics), but it still worked out and it's totally wearable.
Once you start to realize that it's not that hard to mend things... It's like a super power.
I have a couple of really nice REI camp chairs and one of them got several holes burned through it by flying embers around the fire one night, so I patched them. I didn't even try to make it match, I full-on chose a totally different color patch, and bright red heavy duty thread, and it looks badass.
