I think it was over on Pinterest I saw this idea with paint swatches. Well, whilst looking for mine I came across these strips which I thought would do just fine.
The strips were cut in half and trimmed at the top. The protectors around the hole - I cannot for the life of me remember what they are called - come from the Magnolia Romantic tag die. The blue bookmark has images from an old Hero Arts stamp set and the orange one was stamped using Flourishes Fine Herbs stamp set. The sentiment is also a Flourishes one from the set called Tag Lines.
