Yea, it is a pretty cool way to foil a lure. I got the idea from engineered angler on youtube.
The head transition was very tricky. Again, I've only done this a few times, so there might be better ways to do it. Basically I foiled the scale pattern right up past the area where the gill plate would be. Then I made a quick stencil for the shape of the gill that I wanted. I carefully traced it onto the foil scales, then using a very sharp knife, i cut out that shape, and peeled the cut offs of the foil scales. . Then I cut a flat piece of foil to fit in that spot using the stencil and carefully fit it into the cutout spot on the lure. It is a pain, but can look super cool!
Here is another one that worked out good too. I ended up using two separate pieces for the gill, then the head. You can kind of see the overlap, most of which i was able to hide with that black paint to accent the gill. You can see better on this one too, how I highlighted the scales with black paint, then wiped the foil scales down, leaving just the edges black. Then I epoxied over the whole bait, before adding any more paint.
Looking back at it in hindsight, I really left the head/eye area blank. lol. Should have added more detail. There is still time to I guess. haha This is my version of a Manitoba "greenback" walleye.
