The same store was selling lots of cute tiles, and the little ones were 50c each.
So, I bought some grout in a tube, and Jon had a tube gun thing he let me use (read: set up for me because it was confusing)
and I bought 28 tiles (actually 29 in case one broke, but none did.)
I sanded the shiny frame on the mirror so the grout would have something to stick to.
and then I put what I thought was an appropriate amount of grout around the edge- enough to stick, but not so much that it made a mess.
I didn't even need to use spacers or actually grout in between them, because it so happened that it was the exact right size to fit them on without any spacing and no overlap around the edge. It was like that mirror was MADE for those tiles. I should've bought a lottery ticket that day since that is super lucky.
YAY! fastest and easiest project ever.
And it cost about $18 including the grout, but not including the cost of the mirror, which I purchased at a burlington coat factory home department about 10 years ago.
... Why did I keep moving that dumb mirror?
Well Im glad I did.
