is there a adhesive backed netting available or whats the best way to use netting to put a scale pattern on? i'm not steady enough to keep it from smearing when painting.

I gather the netting at the bottom of the bait and secure it with clothes pins.  Other guys attach the netting to a wire frame or embroidery hoop and hold it against the lure while shooting (you need 3 hands or a lure holder to do this).  I've never found an adhesive that wouldn't stick on the lure surface and ruin the paint job.
