Cut a six or seven inch square section out and use it as a gripping device for removing stuck lids on jars.

I can give you one too! If you buy a 'router mat' you pay more, but if you go to the homewares section of wallyworld and get the same as shelf liner...its a lot cheaper!

Carpet padding works great also. If you know someone having carpet installed grab the scraps. They also work great for sanding small items.
