Thank you so much for your critique! The piping took me about 4-5 hours total, and it did hurt a little ^_^ But don't they say pain is beauty or something like that. I see what you mean about some of the details on the larger piping being done in a smaller tip and I will definitely keep that in mind for the next time. There isn't a sink hole on the top layer, but the outline for the topper placement so the design would curve around them. I did not post the picture with the topper because, it makes me cry inside a little. The bride chose two Simpson's figures to go on top. You are very kind, though, and I just wanted to thank you for your very thorough critique!
