Thanks for the kind comments everybody!!
Hey lovely Ralph, glad you liked it!
I'm still tempted by the evil try-it-out-(oops,itlooksworse)-devil
to see how it looks with grout, but maybe sanity prevails...
HSG, not sure if you'll check back on this thread, so I should probably try the glass board : Does sealing the glass change it's surface from matte to shiny? That might be nice, they have much more vibrant colours when they are wet... Thanks so much for the advice!!
