Sculpture and Upholstery, the bench #2

Upholstery foam is easy to cut if you have the right tools. I use a sharp fish fillet knifes. Draw a line all around the block you want to cut, keep your knife level and keep an even tension on the foam as you cut.

Here are the two knives I use and their cardboard sheaths to protect the edge of the blade.

Here's all the foam laid out for the bench seat.
