OK, what's the secret to keeping the parchment from warping when making a color flow piece? I tape the design to a sturdy baking tray, then I try to tape the parchment to the tray over the design. Looks great. It seems as soon as the moisture from the color flow hits the paper it ends up getting wavy. The tape doesn't actually stick to the parchment so it doesn't keep it pulled flat. I am using Wilton parchment paper. I tried to take a photo but it doesn't show up very well. If you look at the right side of Elmo he has a big wave running vertically. Still usable but I'd like to know how to prevent this. TIA!

Most parchments have a silicone finish, so no, tape doesn't stick well.

Baking trays can have some give, too, if there are temp changes.

Better to use good quality wax paper, cellophane, or acetate taped onto a smooth cutting board or piece of plexiglass.

Also, it's necessary to work quickly on these, with the tip (very small tips burst any bubbles that are in the icing) buried in the icing so that you puff it up from the bottom. That way, you don't get dips where the icing has dried at different rates.

I only use parchment paper, I never have any issue with it. I have never used the Wilton brand the one I purchase is not sold on a roll it is in sheets maybe that helps it lay flat.

Thank you. I guess I'll have to try out some different papers.

I do mine on plastic page protectors.

I do mine on Wax paper and have done almost the same elmo design actually (it broke a bit when placing on the cake, good thing I do cakes for free!) As Rae said (who would definately know better than me), keeping the tip buried gives a smoother finish.

I actually made 4 elmos just in case
