I don't really have much need for a handy supply of pins but if I did, I'd keep them in a dish like this.
These Stripe-tastic pin dishes were made between 1954 and 1957. Known as studio slipware the dishes were made by (you've guessed it) Hornsea Pottery.
The flared black and white stripe design is hand-applied in coloured slip. The softly-curved rectangular dishes are nice, they stand on a base with four small feet.
