I’d like to think that if I ever did a ceramic-tile project, I’d use gems like this.
In perhaps 7th-grade art (can’t remember), the assignment and supplies were for making a trivet with little pre-made tiles (tiling, then grout, that kind of progression). Except. As as I recall, the options were from The Ugly Assortment (my judgment). Like medium brown with YELL-ow flecks…ick.
These, HOWEVER, are lovely. Gems. Not good for a trivet, but much better aesthetics. IMHO.
