LOL. I have some acrylic potholders that my great-aunt crocheted for me; we use them for hot pads and it never crossed my mind to worry about them melting!
What a big mess we'd be in now if they did! (We've put pots right from the stove and pans right out of the oven on them!
It was looking at those during dinner, coupled with the notion that I wanted to buy some placemats anyway because I'm tired of having to clean the table all of the time. Not that I wouldn't have to wipe anymore with placemats, but it would be easier to clean up after my preschooler.
Since I have so much acrylic, I could make a bunch of them and just throw them in the wash every night. Then I would only have to do a quick wipe across the table instead of the scrubbing I do now.
I can practice different stitches, use up some stash, and get the benefits of placemats without spending any money! Sounds like a great idea to me!
Before I go off on my own, I wanted to see if there were any placemat patterns that could help me with sizing and edges. Those links have already been very helpful for me. Keep 'em coming, if you have any more!
