If the elastic on underwear is still good, but the fabric is falling apart, you can use this technique to re-make your underwear from an old t-shirt.

It took me about 5 hours to make 2 undergarments, not including time to take apart the old underwear. This will probably take less time with experience. Based on time alone, at $20 per hour, these undergarments cost $50 each. But the actual material cost was $0 because I already had old t-shirts and underwear on hand. So if you have spare time, it is a very economical and easy project.

    Never would have thought to do this (my elastic tends to retire first – and sometimes in the middle of the day, which has left me in a pair of droopers!). Great recycling project! Super resourceful, is what you are.

    This is so good. And exhaustive, but worth it.

    Thanks for posting. I’ve been thinking about making undies lately and this is a great way to re-use old elastic

    Best part about sewing your own undies – because YOU determine sizing, elastic won’t cut into your skin, fit is looser and extremely comfortable. You can use any knit – I like to use new/old tee’s/clothing/anything that strikes my fancy. I prefer to use men’s L-XXL sized cotton knit tees/polo shirts (have nice patterns). l /can make about 3-4 pairs (use sleeves for the crotch pieces. Been making them for about 4 years now. I’ve made them for other people, and also like making boxer shorts (very easy)

      That’s cool. If you have some ideas that will make the technique feel free to explain how you used to do it and I can incorporate your input into the technique.
