I've been spending time (and my fabric stash) sewing sock knitting project bags. They're approximately 8" deep and 5x5" across the bottom. Here are a few photos of the finished products.
And I've opened up an etsy store where you can view even more photos and purchase the bags! It's OliviaKnits of course! I am planning on making some zippered bags and larger totes as well but since the sock projects are near and dear to my heart I started with those ones first.
