Not sure what’s exactly "Mod" about these – I think they just mean 60s-inspired. In fact, these Mod glass coasters were created by artist Sarah Hirneisen based on vintage textile patterns she had encountered.
The kiln formed pieces – in shades of ivory, blue, green and orange opaque glass – feature silk-screened glass enamel designs. Handmade in the US, this set of four coasters is certainly a great way to brighten up a dull coffee table. Available online for $45 (wich is around £25).
