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 19cm-29.5cm, ribbon size 3cm (height) x 7cm (width) x 2cm (thickness), collar width 1.1cm, bell diameter 1.3cm. It has a safety buckle for your cat's peace of mind (⁠＾⁠∇⁠＾⁠)⁠ノ⁠
