It was my birthday recently and I bought myself this:
I'd been wanting a larger rotary cutting mat and this seems perfect for me. I can use one or two sections on my sewing table. I can also stick them all together and cut on the floor or a large table in my building's community room.
I have a knit dress to cut, as soon as my neck pain subsides. Imagine cutting an entire garment at once!
Only issue: they stink. The cure is soaking them in a tub in vinegar water. Except I don't have a tub, only a shower. Hmmm...
