Baseboards are being added to the shop later on today. These will be cut pieces of cement fibre tiling board and lightweight compressed foam board, Marmox. The cement fibre board is water resistant and you have the option of a primed piece which will be water proof. This board is suitable for exterior work.
The Marmox board is light enough that it can be used where you want to hang your mosaic on a wall.
The price for the 6mm thick cement fibre board will work out at 25p per 10cm x 10cm square
The 10mm thick Marmox will be 30p per 10cm square.
If you want specific geometric shapes then this is done for free, cutting the edge to make it look like a fragment will be another £1.00 on top.
