DIY | Geometric Coasters

When I was younger, I thought coasters were the dumbest, most useless things you could buy. As cooler days arrive, I like to keep a mug of tea or water beside my desk to keep hydrated. It was all fine and dandy until those unsightly drink rings kept showing up and I was scared of putting a hot cup on glass...leading to the revelation that investing in coasters might not be so dumb and useless after all.
