Pauline it was chefmaster 7386 violet, it actually did it to me twice, first time I thought it was because it may have got a little direct sunlight, with the shoe box though, I didnt finish covering the cake till way past dark, and was up early efor light, and there was no lights left on during the night. Dont know if it was a bad batch but not going to risk buying another one to test either lol
