I did pull out my brand-new 17" rotating cutting mat and used it last night. It seemed to cut much better with the same rotaty cutter. So, I'm assuming the other 2 are old. I've seen where people rejuvenate them by soaking them in a tub, etc. Have any of you successfully done that? Does it enable you to use them longer or is it worth it? Lastly, if it's time for them to be repurposed........what do you do with them? They are the rotating ones, so can't flip to the other side. I guess I can use them to protect the surface of some of my sewing room furniture (but I've already gone some old mats there). How long do you keep yours? Did mine have a good run? Let me know your thoughts. I just don't want them going to the landfill without squeezing out their last bit of usefulness! Thanks!
