Non-Slip Acrylic Templates

I've been using a lot of acrylic templates for cutting fabrics lately.  One thing I hate about acrylic templates is how they sometimes slide when you're cutting.  And of course, it always slips at just the WRONG time in the cutting process.  There are special non-slip dots you can buy that help with the slipping, but they are just expensive for the number of dots you get in the package.  So, my cheaper solution is the Duck brand rug tape you can buy at Walmart for about $8 per roll.  It sticks well to acrylic, lays flat between the template and your fabric, and is very effective in keeping those acrylic templates from sliding while cutting!  The best part is that the roll is huge and should last forever.
