So I recently bought a proxxon hot wire cutter in a fit of realising I'm hitting 30 and have never made a foam ruin.
Using my very big jiggly totally not smooth wrinkle less brain I decided the best way to go about doing this was drop a hundred quid on something I'd never seen before.
Well after a few hours this afternoon I'm happy to report I kinda know how to work it.
My goal now is to melt my way through many a sheet until I have a 3rd ed esque city
