This is the perfect sized tote for your sock-in-progress. (And a fun way to tell people "I'm a sock knitter!" You get Loopy in his red socks, proclaiming it to everyone.)
Nylon handles, zipper top. 12 x 7 1/2. Keep one filled at all times to grab and go when you're running errands and might have a possible wait time.
