I need to replace some elastic waistbands but I put all that away on a high shelf and stuff on top of it -_-
Edit: I grabbed it down, and I had already done the worst of it for one pair of pants. (The elastic was folded over with the top of the pants and both sewn in together, probably for speed in a factory, meaning I had to unpick the entire waistband the whole way around. I had then handsewed it into a lazy but serviceable casing so the next time I need to replace or adjust the elastic I can undo a few stitches and just pull the old elastic out.)
The new elastic is in that pair now but I haven't sewn the hole up yet. I'm going to wear it around for a little while to be sure it's a comfortable tightness and then close it.
Time to start unpicking the next pair.
