Review on 🆔 Density Polyethylene Plastic Sheet: Unaltered Natural Raw Materials by Allan Lambert

Can't order a *really flat* piece of plastic anymore? This was purchased and shipped during the cold winter months, packaged very well (but respect for that - excellent packaging), shipped quickly. When I opened the box I had high hopes, but the sheet has some curl. And I need a really flat sheet for my project. So I'm off to experiment with a very low temperature oven. I'm hoping to find large enough (and shallow enough) baking sheets along with parchment paper to keep everything neat and separate to see if I can manage what I need.
