Hi
I am making a hat box cake in a few weeks. All fondant. The lid just rests against the side. I have no idea what I should use to make the lid out of. And how would I fix it to the side of the cake. I attached a picture of a similar cake, the only difference is the color, and the one I'm doing is a 10 inch round instead of square. Any help would be greatly appreciated. I have been cake decorating for only 6 months.
Thank you!!!

You can cut a piece of half inch foamcore and cover it in fondant or you could buy a 1/2 inch round cake drum and cover that in fondant. Just prop it against the cake when it's on display.

You can also, use g/p and cover a pan the size of the cake, round or square or oblong. Powder sugar the top of the pan, grease the sides of the pan half way down with crisco . Roll out the gumpaste , can be g/p and fondant mixed. Cut enough to cover top and sides(not all the way down. Use a ruler, exacto knife and cut clean edges all the way around . leave to dry on pan. next day take off carefully and leave to dry for couple days. Dust off powder sugar, and wipe clean with a paper towel , with crisco on it. Wipe really clean, the use plain paper towel and go over that. This will make it have a very professional look. hth

Those both sound like good ideas. Feeling a little relieved already. Speaking of gumpaste, up until now, I have been using the store bought pre made gum paste, but I often hear of people making their own. Any direction on this?
Thank you sooo much!!
