If you should have problems with you paint running or dripping while curing, you can hang them by the eye of the hook with a piece of wire (I use christmas tree ornament hangers). This way if the paint should run or drip it will go to the back of the jig and won't mess up the head.

If you apply multiple coats of powder to your jigs (I do this a lot), curing inbetween each coat will also minimize running and dripping.
There's a lot of trial and error that goes along with pouring and painting jigs, but I find it very enjoyable!
