I crocheted a ribbon from cotton yarn and made it into a collar. This time, I used a blue ribbon (⁠◍⁠•⁠ᴗ⁠•⁠◍⁠) Since I haven't used any adhesive, you can wash it if it gets dirty. The size is: length, 19 cm - 29.5 cm; ribbon size, 3 cm (height) x 7 cm (width) x 2 cm (thickness); collar width, 1.1 cm; bell diameter, 1.3 cm. It has a safety buckle for your cat's peace of mind (⁠＾⁠∇⁠＾⁠)⁠ノ⁠
