I made a cover for "Azuki no Chikar" (a Japanese product for neck and shoulders) by hand. There are 5 pieces of this fabric in total. This is a stretchy, soft fabric that stretches well horizontally. I made it to fit my "Azuki no Chikar," so there may be some discrepancies. The opening has elastic because it will inevitably stretch with repeated use. Because of the elastic, you cannot microwave it with the cover on. When putting it on, place the main body on top of the cover and insert it in the order of the top half, then the bottom half. The corners, which are in a U-shape, are sewn with about two stitches for reinforcement. You can wash it in the washing machine using a laundry net. When drying, it tends to stretch horizontally, so I recommend drying it vertically. There are traces of white pen marks and temporary adhesive, but they will mostly come off with washing. This is a sale of the cover only. This is a sample image. It is made of the same fabric, but the pattern appearance differs. It is a heathered dark gray. The color may differ. Small brown cotton fluff particles may be mixed in. Please refrain from price negotiations for single items. If I can package multiple items together, I will discount the shipping cost.
