Ok, I bought this to do some textures... And I found it very similar to my cutting board, so now I use it as a mini work mat for working with clay while sat in front of my PC (desk space limited) Sorry its no help on how it does with carving. But it does make a great mini work mat :) I guess I can only mark it 3, since I have no experience with it as a carving texture.... Sorry, but a heads up for those with limited space :)
Rubber sheet - make your own texture sheets!
It is also a great work surface! You can draw on it with a pencil (so you can rub it out and wash it off - ready to use again) and use as a secure base surface for syringe work. The syringe will stay put on the sheet, until it is completely dry.
