So...it's BBQ time here.
It was time to get new grill mats, and I found a great deal on copper mats.
Also...
I was using my wool mat next to my sewing machine for quick hits with the iron instead of finger pressing. Then I saw the copper grilling/baking mats, and decided to grab one & lay it on my wool mat & iron the finished blocks on top of it. (I wanted the blocks very flat, & sometimes I get too lazy to get up & go looking for the starch).
anyway....wow!
super crisp, super flat seams! It allowed both sides of the block to be ironed at once. And, even without the wool mat, this thing works great on the ironing board.
this is where I found the mats:
