The tawashi has gained much popularity over the years. Originally from Japan, today knitters and crocheters all around the world have joined in the fun. And who wouldn’t like the idea of making their own scrubbers, made of 100% acrylic (read:ridiculously cheap) yarn, and save the environment all at the same time? It can be used with or without detergent, too, so it not just helps save the environment, but gives your everyday budget a break, too.
