Hello! It has been a while since I have done a frozen buttercream transfer. So I have a few questions. First, how much in advance can you make a buttercream transfer? On the tutorial that I read and that I have used in the past, she uses a black to outline the character and normally I do that too. However this character (school mascot) does not have black outlines. SO what do you do in this case? Can you just use the same buttercream that you are making for the transfer as the outline? I need it to be blue. Any other tips??
