I used to have a thimble stall at a series of collectables fairs where one of the pre-requisites was to produce a display. The fairs were themed and one of my most popular displays featured Christmas thimbles. It was effectively simple, using a small Christmas tree as the backdrop and displaying the colourful thimbles that depicted Christmas. From that display seeds were sown as to how easy it was to have a collection within a collection. Thimble collecting with a theme is really popular. One of the most collectable is the annual Christmas thimble.
