Found these on the Country Sampler website.
They look relatively easy to do. I love the red ticking napkins they show in this photo as well. Pick up some ticking at the fabric store when you get the fabric to make these adorable coasters.
Country Sampler suggests displaying them in a woven basket on the dining table, using one as padding beneath a glass vase, or feather into your decor in any spot that needs a little patriotic perk-up!
