118x11.8 Inch White EVA Foam Sheet, 5mm Thick EVA Foam with High Density, Large Crafts Foam Roll for Art Craft, Cosplay Costume, DIY Projects

I love this foam so much, it's perfect for my crafts! it's easily flexible and super easy to cut and shape.

I find it a bit expensive for what you get. It will keep a bit of the curve once you unroll. The last few inch won't look as good as the rest because of the crease. where they started to roll it.You still get close to 10ft (but not quite), and it not quite 12inch width. But anyway, for my purpose, it was ok in the end.

This white, thick high-density craft foam provides a base for all your craft and cosplay plans. Measurments are as posted, with the thickness being just under 1/4" and just under 12" wide. Cuts easily with scissors, or steel rule dies. It's flexible and easy to manipulate.One thing I did notice is that when I went to test the foam's give and density, my fingers left a permanent impression, which may become an issue depending on how much handling you have to do to make your piece. I don't have a project on the go right now, but I am looking forward to using this to fabricate hard to create elements in the future.
