I need to line my round cake pans with baking paper. My recipe book shows how it is to be done, by folding the paper into a cone, and then cutting it according to the radius of the pan. Unfortunately, the instructions are poorly worded, and the picture is confusing. I have been at this almost 3 hours, and I know I won't be able to sleep until I find the answer. Please, would someone be able to tell me how this is done? I know there may be another way to do it, but I do not want an approximation. I want to do it the RIGHT way and PERFECTLY. Please, my geometry and spacial manipulation skills are 0, so a highly detailed explanation is required, since I am obviously too stupid for the abbreviated one found in my book. I think I am going nuts. I want to sleep, but I can't until I know I can do this! :x
