I designed and sew a polka dot pen case. It is small. The zipper is just 14 cm long so this item is usable also as a small pouch. I used polka dot fabric I've inherit from my granny and recycled zipper. It was fabulous to find a circle decorated black zipper from my storage box! It is like made for this cute pouch project. I don't like polka dots a lot but with tiny portions it is quite chic.
