Tried using this setup to make stencils for some of the lure blanks I paint and it worked great.
Plastic milk jugs can be used to make some really nice stencils. Using a heat gun the plastic heats up quickly and gets clear when its ready to be placed over the lure body. The plastic forms to the lure body very well and is easy to cut into patterns.
Cake tin with holes drilled into the top
Popsicle sticks glued together to make a frame for holding the plastic
Gator clips to clamp the frames over the plastic
Milk jugs for stencil material.
Hope this helps someone save a few bucks and make a few nice baits
