Hi! I'm searching high and low for something and I don't know where to get it! Maybe someone might know... I need some inking slabs/sheets for printmaking (collographs and monoprint). We always used a sheet of plastic at university, maybe 5mm thick or so, to roll out the ink with rollers. I know you can get the glass slabs, but they are expensive, so I'm looking for the plastic kind. I found a big sheet of plastic at B&Q but it's impossible cutting it up into pieces! Does anyone know what I mean, and where I can get these from? I can't seem to find them online or anywhere!! Thank you in advance!
