While talking to the OLFA dealer at the Mid-Atlantic Quilt Show a couple of weeks ago I learned that you can extend the life of your OLFA blade by hydrating your cutting mat! Who knew that a "dry" mat dulls the blade!?!
The vendor, Charlie, was full of helpful information and did some great demos. OFLA tools are some of the best, and it's nice to get some inside tips on how to care for them. He also told us how you can renew a mat that has been warped (see his website if you need that info).
Here is a photo of the printed instructions he was giving out for wet cleaning your cutting mat.
