Im making a "Roller Derby Wedding" cake and its been requested that there be a fishnet pattern on the tiers, and im at a loss as to what the best way to go about it would be. I first though of piping it, but it seems like that might take forever to do and, my piping skills are weak at best. Then I thought maybe I would paint it on. My only qualm with this is that how would I get the pattern to look right wrapping up on top of the tier?

Anyone have any ideas or suggestions? please please!

Don't know exactly what you have in mind, but you might consider Sugarveil icing. Check out the bottom right example here

This can be done without the dispenser system - just a piping bag or icing comb to make straight lines of the flexible Sugarveil and then make dots to hold the separate lines together.

A fishnet is basically just a diamond grid pattern. Many press a straight edge into the icing in the pattern. That might look nice on a wedding cake as just dents, or you can go over it with a piping bag to make it raised.

Wow, that sugarveil stuff looks amazing! I really want to try that... unfortunately I dont have time to order it for this cake. So I think Ill try the indentation thing.

Thanks so much!
