I can't remember where I saw this, but adding some of that gripper shelf paper to my cake carrier changed my life. Seriously. I take dessert a lot of places and up until last Christmas I did not have a cake carrier. I thought my cake carrier was awesome, but then I read about putting this non skid shelf paper between the cake and the carrier. It makes a huge difference. No more cake smears on the sides of the cake carrier. It's so good!
