I made a flat pen case using fabric with a Scandinavian design, inspired by ItoIto-san's videos. It has a pocket on one side, which I think makes it very easy to use. The fabric is thin flannel. The zipper is beige. The lining is light gray. Size: Length: Approximately 18 cm Width: Approximately 7.5 cm There is no gusset. The pocket depth is approximately 10 cm. This was made by a handmade enthusiast using a home sewing machine. I made it carefully, but since it's handmade by an amateur, I would appreciate your understanding.
