I haven't done any 3 snowball ...
Thanks for the tut - I just might this year!
I like the 2 snowball method cause I want them to be short and round but not too big.
I make two separate fat round beads next to each other - one the top smaller than the bottom (very close - so that I can melt them together) before adding the decorations.
Sorry for the quality of the photo - the only one I had - with (some ornaments?)
