Metal trim for glass mosaic tiles

Hi all,
I'd like to use glass mosaic tiles (on a mesh) for the back splash of my bathroom sink. I have used metal trims around the bathtub tiles, and would like to do the same for the sink back splash, but these glass mosaic tiles are much thinner (1/8" ?) than regular tiles, and I cannot seem to find metal trims that are smaller than 1/4" thick at Home Depot and a couple other local hardware stores I looked at.
What is the best way to do this? Can buy a smaller trim and if so, where? I tried putting a lot of glue behind the tile to increase the thickness, but the mesh (along with the tiles attached) started to bulge and slide, due to the large amount of glue used to achieve the thickness that was needed to work with the 1/4" trim.
Any suggestions would be greatly appreciate.
Cheers,

how much do you need to build up? glue/nail lauan or plywood to the wall to make up the difference?
