I saw some posts
online where people had used domestic irons to laminate plastic bags together to make boards and more substantial bag materials. I did have a go myself, but came to the conclusion that it was a bit
energy extravagent. My board wasn't very well consolidated either.
I do quite fancy getting set up with a shredder and extruder to make CAD models from plastic, but priorities mean my time and money is spent elsewhere! In the meantime I annoy my husband by collecting
milk bottle and other plastic caps for future use maybe.....
