Does your bandsaw have two or three wheels?
If it's an old 3 wheel design, I found that using some masking tape to affix the band temporarily to the upper wheel helped me wrangle the rest of the blade around the other two wheels and the guides.
Fussing with this configuration made me realize very quickly that I wanted a two wheel machine. So now I have a 14" Delta with a riser block... an enormous step up from my introduction to band saws.
