Instead of a specialty non-slip pastry pad

Instead of buying a specialty non-slip baking liner, $20, to roll out your pastries (I use mine for pizza dough)
consider buying a roll of non-adhesive, reusable shelf liner for $6. From this slip-resistant, 5 foot roll, I cut 3 mats that I can use for rolling out pastries or playdough.

I do not assume this material is food or oven-safe, but it will keep my parchment paper from sliding around when I roll out pastries!

The label even says it is washable!
