Dry them, then vac. seal them, and toss into the freezer. If you don't have a vac. sealer, use zip top bags, and try to get as much air out as you can. This is how I do mine. I bought a Renyolds Handi-vac setup. It's zip top bag with a "valve" that you use their little vac pump with. I weigh out 1oz of dried hops and then vac-seal in 1gal bags. You'll be able to use your hops as needed.
Hope that helps.
