Le Prevo offer a service where for £60 (£45 + £5p&p + VAT) you can get a 4"x5" plate etched for embossing your own leatherwork. This works out at £3 a square inch.
I suggest that if we group together we could get this plate ordered with multiple designs on it. Of course, it would have to be cut up & posted but for under a fiver you could have a custom stamp made
So, for 20 sq.in. we need 20 buyers. Of course, if you want multiple inches that's no problem
Copy & paste & add your name. Once we're up to 20 names we'll start sorting things out.
