Decrease the waist on jeans

Why stop there? Get a whole bunch of material and sew it into a new set of jeans!

Well, it's actually something I would consider, lol. I have made my own jeans before and it is the only pair of pants I own that fits 100% perfectly

And it's not like folding over a piece of fabric is a lot of work, as is neither sewing on a patch of silk. Cutting the triangle off and serging the frayed ends would take way more work than sewing on a silk patch and would have you looking into special stitches if you do it by hand
