Under-the-glass mat (FIMO millefiori)

This is a polymer clay (FIMO) mat, to be put under your glass to protect the table. Additionally, when backlit with a lamp, it makes nice visual effect, as it is made of semi-transparent FIMO.

It is made using the millefiori technique, which is a descendant of the glass millefiori, used for many centuries with glass (most fameous – Venetian glass).
