Just stumbled across vialetter Basically you can order from 5 typefaces to spell whatever you like. Quite good for a different style of sinage or to decorate a studio for example. You can choose the font and it'll price it up all live on screen which is handy. The letters (capitals) are around 12cm tall and the lowercase letters are proportional to this (as an idea an 'a' in bodoni is 7cm tall). All the letters are 10mm thick and are made out of the same material which is a synthetic hardcore foamboard. some of the letters are out of stock though, which is a shame.
