My friend gave me the best knitting project bag I have ever used. The truly unique feature of this bag is the plastic window that allows me to see which project is in the bag without opening it. I never have just a single knitting project going at one time. Sometimes I lose track of which project is in each bag. This bag eliminates this problem. The craftsmanship of the bag is excellent. I love the zipper with pulls at each end at the top of the bag. The bottom of the bag is constructed so that the bag remains upright even when empty. There is also a detachable wristlet strap to make it easier to carry when travelling and an internal pocket to hold your notions. This bag is sold at my friends Etsy shop. She makes all the bags herself. She designed this bag for another knitter friend who used to carry her projects around in transparent plastic bags. These bags are available for sale at her Etsy shop at www.etsy/shop/Butterflysisters.com.
