These project bags come in an array of colors. They are waterproof so that you can take them with you on the go. You can tie them onto your handbag or briefcase, to take them with you to work or even just going out for the day. You can carry one with you to go on vacation. They are 12”x14” and were specially created long enough to fit straight knitting needles. I have many craft projects that I am working on all at once and I have several bags that I use to store them all in. I decided to offer these project bags for sale separately, as well as include them with the kit, because I know how useful they have been for me. I have at least 10 to 15 project bags. I also use them to store all of my yarn. There are so many uses for these bags. If you use your imagination I am sure that you can come up with so many ways to use them that I hadn’t even thought of.
