The ingredients are:
1. Blank wooden or plastic lure body
2. Netting, the same type you shoot paint over when painting scale effects onto a lure.
3. Foil...there are two types as you probably already know...the aluminum foil we all use in the kitchen and the foil that comes on a roll from a hardware store or Walmart, which is used to tape furnace ductwork together. The furnace type is far superior (again thank you, Husky for introducing me to this stuff). The furnace type comes on a roll. You cut off as much as you need and peel a paper backing from it to expose the glue that is already on the foil. It stretches a bit, which as Husky told me, "you will appreciate that."
4. Spray glue for the netting. You can use almost any type of all-purpose sray adhesive. I bought stuff called Duro All-purpose Spray Adhesive from Walmart, but its not special, just a run of the mill spray glue.
5. Razor knife, razor blade, or Xacto knife. I strongly recommend the use of an Xacto knife because you can cut a precise line when trimming the foil.
(Forgive me if this explanation is too elementary, I struggle writing step-by-step instructions.)
Here's how:
Cut two pieces of netting long enough for the lure blank and wide enough to wrap completely over the top and bottom of the lure. You'll place one piece on each side.
Next lay the netting on a clean piece of paper. I use ordinary printer paper from my computer.
Spray one side of the netting thoroughly with the spray glue.
Apply the netting to lure blank. Be careful to align the pattern on the netting evenly so that the pattern runs along the lure evenly, not tilted sideways, etc. Make sure it sticks properly. If it doesn't peel it back a bit and shoot the netting again with spray glue. Don't worry about getting a bit of the glue on the lure. Won't hurt anything.
Trim the top and bottom of the netting off right down the center line of the back and belly of the lure.
Now apply the netting the same way on the other side of the lure. Trim back and belly down the center line. Try to make it touch at the seams.
Next cut a piece of the foiling and place it over the netting and carefully smooth it down with your thumb. NOTE: Be a bit careful here. The foil scratches easily during this process and even your fingernails will etch it easily, so use a bit of care.
The foil can be slighty stretched but don't be too aggressive because any minor wrinkles burnish away easily when your done.
Again trim away the foil along the center line of the back and belly. Its okay if it overlaps a bit. The seams also almost disappear when burnished.
When your done, take your thumb and push the foil down into the voids in the netting to highlight the scale effect. Take your time, this adds a tremendous amount of detail to the scale effect.
Burnish any crease and all the seams with a smooth rounded object. I use the shaft of a screwdriver. Works fine. I know everyone has their favorite burnishing tool though, so use whatever works for you.
The furnace type foil can be aggressively burnished with no ill effects.
I hope that helps.
