Not sure quite where to put this thread, so I figured general?? Ok..I have been making the car air fresheners for 2+ years, but silly me had a brilliant idea last night (or..so I thought!) As of late, the cookie sheets I'm using sometimes seem to leave a sliver streak on the back of some of my car fresheners (guess it's time to get new ones). Anywho, I'm thought..hmm..what can I do so it doesn't leave a mark? Aluminum foil! Yep, I'll try that. Ummm...DON'T! That was the most stupid idea I have ever had! hahaha The aluminum foil sticks to the back of the fresheners, and you have to carefully peel it off. Pain in the butt! So, that idea out the window! I ended up ruining half of my batch cuz the foil wouldn't peel off :embarasse Wanted to share my experience in case anyone thought of the same thing! hahaha
