How do you store double jig head rigs?

I use quart or sandwich bags to store all of my stuff, popping corks with leaders also. Wrap in a big loop and put in individual bags.

I just tried these for my surf fishing rigs. They would work fairly well for what you are making. Fit in a tackle box/bag a lot better than the cut pool noodles which was my old way.

Wine cork and zip lock

I will use a piece of 3/4" styrofoam cut about 2" wide and what ever length you want. You can stick one hook in the foam, and start wrapping. Don't stick the second hook in the foam until all line is wrapped. Then assuming you have a loop tied in the end of the line.... put the second hook thru the loop and secure the hook in the foam.

You can store several rigs on each piece of foam.
