Place mats for lining molds

Help...has anyone tried lining molds with placemats or those plastic thin cutting boards? Do they work? I have my silicone ready, and am going to try this week, but it has a little bit of a texture on the silicone and I'm worried that the soap may stick...does anyone know if it does?

I have not tried this, I wish I could help you on this one. Hope someone comes along that can help you!

The thin cutting boards work very well. At dollar stores here they have thin plastic mats that are pretty big, they call them activity mats, they were awesome. I can leave long sides on my log molds and make hand holes so I can pull the soap out.
