Really been interested in making my own lures. Particularly ones made out of common things you might have around the house. I made a spoon the other day out of a teaspoon someone threw out at work. cut the handle, sanded it and drilled holes in the top and bottom. Added a treble hook and a swivel and it looks good. Haven't fished it yet. Will update on it's effectiveness when I do.
I found this article that has some very interesting ideas for homemade fishing lures.
