Go with bright and fun, retro, or anything else. The coasters look great in many fabric styles and color combinations. Match your decor, or make a set for a particular season.

The hexie centers are great for showcasing a lovely fabric. Or, do a bit of fussy cutting to accent special motifs.
You can also do a bit a big-stitch hand quilting, as in the following coasters from Sewing Room Secrets.
These go together so quickly that you’ll have several done in just a few hours. A set makes a lovely gift, too.
The tutorial, from Canoe Ridge Creations, does not specify how large the finished coasters are. However, they appear to be about 3 1/4″ from flat side to flat side.
