Hi

Can someone please explaint to me what you do in cases where you are tiling a wall and the tiles used have different thicknesses. We are currently tiling our bathroom and have purchased two types of tiles; one has a thickness of 10mm and the other which is a mosaic tile has a thickness of about 4-5mm. How can you get a flat even finish, is it merely putting more adhesive under the thinner tile?????

HELP !!!!
