Gelli-print preparation

Preparing for a gelli-print session.  I wanted to include some lettering in the next belli-print experiments.  I've had badly eroded lettering on some gravestones in the back of my mind.  I hadn't quite decided how best to approach this idea, so these were a few of the letters I've cut to try out.  It was quite a fiddly, time consuming job so I'm hoping to be able to save them and use again.  I dare say there will be cardboard letters available on eBay if I have a look.   I couldn't read any of the words on the gravestones so at some point I need to decide what I want my prints to stay.
