H&M website has information on a garment collection program. The company will take any textiles from old sheets, worn-out T-shirts to odd socks. For one bag of garments, the person will receive a coupon for 10% off the next purchase. The collection box is located next to the cash registers. The store is located on Fraser Street right across from the Fraser Street parking garage.
If Scraps and Skeins can't use it, try H&M.
