I tried knitting with two strands held together: lace yarn and superfine yarn. Although it's unused, I've marked it as "like new" because it's handmade. Size: Approximately 50cm (about a regular size) The starting point is shown in the second photo. The stitches may not be perfectly even. This is a handmade item by an amateur. I think you can use it casually without worrying too much. It can also help to calm "frizzy hair" during the humid season. Please understand the above before purchasing. (^.^)
