My mom knitted these and they have been stored in a plastic bag. She was meticulous with everything she made. There was a note inside with the finished length of 8-1/2”. This corresponds to adult (women’s) shoe size 4.5-6.5. They do stretch. These are done with 4-ply. Please see her work in the pictures. Ask before you buy. If this isn’t exactly the size or color, see my other listings.
