I print the image out on full sheet label paper, it has a sticky back but i still use a spray adhesive as well. As for hydrographic film which i believe is water transfer, There are many posts about this subject on TU.
I just super glued the 2 halfs together with the ribbon inside, then quickly squeeze together with a vise, some sections i pinned as well. I would prefer to use the kevlar stuff like the bass pro ones, but so far i cant find a local source.
I had to try making some baits with the new joint style, I like the way they swim, but they are very time consuming to make by hand.
Heres what they look like in the pool
