Has any one here bought and used these templates....They are made of mylar, that is supposed to be heat resistant, so you can iron over them and then they have a hole in the middle for easy removal and reuse.....They were used in a resent Fons and Porter show....found the website, but $15.00 per package....Is there value there, or should I just make my own. Have pattern for a very pretty apring table runner.....
