The GoKnit® Project Bags are made with patterned ripstop nylon and are machine washable. Use the  inner loop to keep your yarn in the bag and use the outside snap loop to attach your bag to other things. The bag will stand upright when on flat surface. The Mini measures 6"x8" and is perfect for socks, hats and starting projects. The Standard measures 8"x11" and is great choice when you need more space for those larger shawls or sweater projects. Your GoKnit bag will squish into backpacks, large totes or luggage to keep your projects close and safe.
