The Artisan Collection from Pink Paislee allows you to customize each individual piece to fit your personal 'crafting' style. You can leave them "natural" as an elegant accent or add color mediums to create unlimited creative possibilities. These products work great with misting sprays, craft inks, markers, paints and various ink stains. Each package includes 16 dimensional foam stickers that measure approximately .25" to 5.75". Acid and lignin free.
