A while back I had a student-Bonnie share with me this great Teflon sheet to use instead of a safety release sheet between my tack iron and the coated collage papers. But I didn't have good results at first...well I cranked up the dial on the Tack iron to about 4 and the heat seem to be transferring through the Teflon sheet nicely.
Then yesterday I had to do some shopping our the local Whole Foods and there hanging in the isle was this packages that looked just like the Teflon sheet Bonnie gave me. ($5.99 for a 13 x 17 inch sheet)
Came home and examined it to the stuff I had purchased on line from Etsy and it's the same things...so what I want to do is share this great deal...though the Avery label sheet that are left over from using your address labels works this is much nicer as it bendable and doesn't tear and can take some abuse and paint or stuff gets on it and you can wipe it right off...Love it.
