Has anyone done this? How do you get it to come out even at the top-- without deforming the diamond pattern or creating big spaces between the diamonds? (Does that make sense?)
OK I just was searching this and I found the answer. I guess it's not as hard as I was thinking. I've always made my topsy-turvy's with angled sides (larger at the top than the bottom). Now I see that they make pans for this and they have straight sides-- VOILA!
