I am going to attemp my first buttercream transfer using the Harley Davidson Log. I have a couple of questions.

What size tip should I use for the outlining?
What size for the fill in?
How thick should the piping be on the buttercream?
Any Tips?
Should the image me a mirror image of itself?

Thanks,
Tanya

I was told a 2 or 3 for outlining and 4 or 5 for filling in.....I am sure there are others that use different tips, but with what I read on here and other sites that is the norm.
