I'm currently crocheting a blanket and, less than halfway through, had started keeping it in just a large plastic bag because it no longer fit in the project bag I have my yarn in. I've done this with every large project thinking that there isn't a fit-all, do-all project bag out there. I was thrilled when I came across this bag! If it doesn't hit the nail on the head, it comes close! I had my tape measure out going through the measurements in the online posting before adding to my cart and hoped it would be just as great as it looked. I haven't used it fully yet, as I still have one skein that's attached to my blanket threaded through the grommets of my smaller bag but I'm confident it's just what I had hoped for. I've put the blanket in so I know it still has room to grow. I love the two zipper layers. The lower zipper opens it all the way to the two sections where the yarn and project will go. The top zipper opens to where there is a flap that has easy to open and close magnetic snaps accessing the large open section while the yarn threads out through the grommets over the yarn section. Not sure how soon the blanket will outgrow the space but it will be great to have it all in one bag for now when I want to tote my project away from its regular spot on the couch in front of the TV. The outside pockets give opportunity for lots of organization. One end has 2 open pockets, one behind the other. The other end has a zipper pocket that can be fully unzipped on top and both sides, making it easy to access the smaller pockets inside, including a clear zippered pocket on the outside flap. The front also has a zipper pocket that runs the full length and most of the height of the front, going up to just below the lower of the 2 top zipper layers. This also opens completely and is divided into other pockets with elastic loops, perfect for several crochet hooks or shorter knitting needles as well as a clear flap covering 2 layers of pockets that are perfect for longer needles or tunision or double ended crochet hooks. This kind of makes me wonder if I can give away my hook and needle cases but I could probably fit both somewhere in these pockets. Lastly, the top lid has a clear zippered pocket that is perfectly sized for pattern printouts or books. I highly doubt I'll ever fill every pocket. The case is not heavy but the fabric and construction seem very sturdy. It can be carried with handles that strap together at the top or with the included shoulder strap. Definitely well designed and well made.
