Precision Glass Cutting Mat's from We R Makers have silicone "feet" to prevent your workspace from sliding all over your desk. Smooth, non-stick glass surface which makes it easy to wipe down and/or scrape off any glue remnants, powders, glitters, etc., when you are finished with your projects. A multi-purpose mat that can be used for whichever project you need to work on from scrapbook pages to stencils to tags. The silicone feet do give the mat a bit of a raised work area, but the feet prevent it from sliding around. The grid marks make it easy to accurately measure any of your projects and keep them lined up.
