Thanks guys.
Yea, thats two air filters stacked on each other.
Funny thing, I went out to test some cranks action at a pond down the road (I was just testing the action not fishing as the I didn't make the lures for myself), and as I was testing the blue one above I noticed that it kept veering to my right as it came in, so I pulled it out of the water and adjusted the line tie. I did this several times and finally got it running straight, but as I'm pulling it in I feel a jerk and sure enough I've got a bass. I don't think the guy that gets the lure will mind to much though. ;D
As for the rest of these lures, I didn't take the two middle ones, The top one is a complete failure( ) and the bottom one needs some work, but I think can salvage it.
