Hi there, If anyone is interested, I would be willing to make a couple of ground glass screens, up to 8x10 for free (well, other than postage costs). I have some glass left over from a recent project, and if I can help a couple of people out then that would be great. As well as being ground, the edges would be cleaned and the corners clipped. If you are interested then let me know and I'll tell you exactly what I'd need to know to make them up. Cheers, David.
