BBQ Grill mats for ironing?
 

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:

Interesting and less expensive!

wow! I might have to try this.

I'll try the mat. Thanks for posting about it.

Very interesting you may have stumbled on something new for all of us. Thanks for sharing. Hummm.....

A couple of things to keep in mind with the BBQ mats - if they are silicone coated, be sure your iron doesn't exceed about 450 degrees F. If they have a fiber weave in them, replace when that fiber breaches the exterior (and don't cut them) - usually that fiber is fiberglass which you don't want to ingest (mostly important for cooking applications, but you still don't want fiberglass in your quilts).

Be sure as OP did to use them on a heat-proof surface like your ironing board or a pressing mat.

Very interesting idea. Thank you for sharing. Now all I need is a grill :)

Good advice.
My grill mats are copper...no silicone, no fiber interior. no fiberglass. Product description says they can be cut into any shape desired. Safe up to 600 degrees. works for me.

What kind of effect will the copper have on the fabrics?

So far, the copper has had no effect at all on the fabrics ...or the burgers :)
However, the fabric does get hot fast, and on both sides at once, It takes no time at all to press. I think it would be very easy to scorch if using starch or steam....I don't use either. Just a quick spritz of water from a bottle.
Also..the copper sheet is hot to the touch wherever the iron was placed, so care is necessary to avoid burns. Just like with a hot iron.
