Did you know that I once had a sewing business. I made a clothing, reconstructed items, and bags. These are few of the bags that I hadn't ever listed on the website. It's about time you got a chance at them. Flattened out they measure 18 inches tall, 14 inches wide but they do have a 3 inch box pleat in the bottom so they will hold your projects comfortably. The straps are 25 inches in length so they're comfy for most people to wear over their shoulders.The material outside is a canvas type material or curduroy (mentioned in the fabric choices). The inside is cotton. It is a soft side bag. There is one row of pockets in each bag. The first 2 photos show the bag's shape and interior.
