I have a favorite (cashmere/lambswool) sweater from a fast fashion store that I sort of let go to seed from wearing it all the time. It now has huge elbow holes that go further up my arm where it gets frayed (along with some holes in the sleeves.)
I wanted to add patches to it. I cut squares from a pair of old cotton/spandex leggings and I wanted to sew it on by hand with a needle and thread, but I've never done this before. I want to do it right and not screw up, but have minimal tools (just two squares of fabric and needle and thread, an ironing board, no pillow even :) ).
Does anyone have a tutorial or have any advice on patching large holes?
