Hey Eddie (if anyone has his email, please can you forward this on if he doesn't see?)
I don't have your email address else I would have emailed you direct!
Would you like some more of that grey card I gave you before?
I've found a bunch more you're so welcome to have.
Also, I don't suppose very thin, colourful silicone (I have sheets of red, orange, yellow, green, blue) will be of any use to you or anyone else?
Very easy to lasercut!
Cheers, Jenny
