Rounded bevel cut on mat - how to do it?

[Jeff Bannow]

At a recent exhibition at the Detroit Institute of Arts, I noticed a very nice matting technique. I'm not sure how exactly it was done, so I'm hoping someone here has some idea. I don't have a photo of it since it wasn't allowed. (No photography allowed in the photography section - how ironic).

So, the windows on the mats were as normal, except that instead of a hard edge where the bevel is, it was rounded over. Does anyone know how this is achieved? It almost looked like a very small rounding plane was used.

To cover up rough bevel cuts I've rounded them with sandpaper.

Sandpaper.

If you are talking about the edge of the window away from the picture you can smooth it with a burnishing bone available at art supplies.

A burnishing bone should give a much smoother result than sandpaper. They cost just a few pounds each.

Burnishing Bone (aka. Bone Folder), I'm not an art major so I just found this out.
