Great tips!
I do use a sticky lint roller on my mats sometimes but I will need to look up the roller you are talking about in the catalogues. I also have numbered my ends and sides on the mats and flip them over from end-to-end or side-to-side. I do have some little pieces that I use sometimes but I don't like the rough edge so I will need to try the honing stone after I look it up to see exactly what it is. Lol! I think of a honing stone as the blade sharpener in the garage.
I have a long die mat that soon needs to be replaced and will remember to cut it for other sizes too.
In August, I am going to a class with an Accuquilt person at my LQS. Part of the class will be showing us how to look at a pattern and figure which dies to use. I'm pretty good at this but I am hoping to learn an easier method.
