Can anyone tell me how to do a piping transfer. I'm sure its here somewhere in a forum, so can anyone direct me that way PLEASE.

Place a piece of wax paper over the design you wish to transfer onto your cake. Take a parchment bag with a small hole or use a regular bag with a tip 2 or tip 3 and fill with piping gel that you have stirred smooth. Trace your design with the piping gel. Note: Be careful to flip your battern over if you need it to face a particular way. Also, it's best if your buttercream has crusted first.

Then, turn the waxed paper with the piping gel on top over onto your cake. Take a small brush or use your finger and rub each line that has piping gel on it until the gel is no longer clear looking. Carefull pull off the wax paper from your cake and now you have your transfer in place. You can now pipe with buttercream onto you cake.

I hope this is what you were looking for?

Here's a tutorial for you...

So then I don't have to let the piping gel dry or anything?

No you don't let it dry.
I find piping gel to be thin and use a tip 1 or 2 - never a three or it will get globby on you.

Thank you so much...
