Hi Brinkley and Members of TF
Theres a real good trick to laying these single
tile mosaics - To get the effect of proper mosaics so you cannot see the main joint lines in the tiles themeselves.
Never install them on a simple block pattern, ie one above the other with ' cross ' joints.
Always install them so that the joints are alway 'T' joints ie 'not one above the other' and try to randomise the spacing - ie position the next row of tiles so that the spacing above the joint is - say 5 mosaics to the left and 5 to the right, then the next row - set the spacing 4 to the left and 6 to the right.
I use window fitters packers - 1mm Green, and sometimes use non and occasional use 1 + the edge of another to achieve the result
Its a little more work but very much worth the effort as the results will look great.
Enclosed - Attached the sort of results that this method produces.
Hope this helps
