One thing we do to stock our store is look through 1,000 lb bales of vintage t-shirts that have been sent to a rag house in Compton who will cut them into rags to be used for clean-up in the auto repair industry. We are looking for shirts we can salvage - by washing and sometimes garment dying to save them from ending their garment lifecycle so soon. Sometimes those shirts can't be saved or we will crop or cut them leaving behind fabric remnants. Since our mission is zero waste we will try to use them in a rag rug. It's a time consuming process but it's fun and requires no machine... just scissors and some safety pins.
I used a tutorial on YouTube to teach myself and I highly recommend this one.
If you are interested in attending a class on making rag rugs in the future send us an email so that we can add you to our class mailing list.
