I have only done one before. I think I used wax paper before, and I just did one and used parchment paper?
Is that going to be a problem removing from the paper when I do the transfer or am I going to be ok?
You should be fine - I have seen it done using either one. I usually use wax paper because I usually have more of it but parchment paper will work too.
Nope, you can use either, you are fine.
