CU EPHEMERA PICKERS PICKS No.11 is a collection of random items and collectables you'd find tucked away in the bottom drawer or in a dusty old storage box hidden in the attic.

This pack of picks include: 25 unique items such as a bird, several advertising ephemera, brooches, buttons, cards, fastener pack, metal flower, metal letter, magazine headline, postcards, receipts, rosette, tag and a ticket

These are great for creating collages, to use as kit fillers or in art journal style projects. There are countless ways to use these finds only limited by your imagination.
