Drafting film is a 100% polyester surface that is archival, translucent and non-yellowing. It provides for a very different drawing experience – it hardly takes any layers, and pencil goes on remarkably dark (my 10H behaves like a 2H would on regular paper!).
Everything smears, which is both good and bad, and erasing works beautifully. (I hardly erase at all on regular paper, but on Drafting Film I find that I draw with my erasers as often as I use my pencils/blending stumps.)
It’s smooth and translucent, and I love the soft look that you can easily create – a look which reminds me of old photographs. The biggest drawback to Drafting Film is that finished pencil drawings are very fragile, so they need to be framed right away.
