Hang onions in pantyhose and they will last for up to eight months
As weird it may sound you can store onions for a longer time by hanging them in pantyhose. Just tie the bottom of a new or washed panty hose. Place an onion into the sleeve and tie the hose. Then place another onion on top and tie it off. Similarly repeat the process to stack as many onions the pantyhose can accommodate. Then hang the pantyhose in a dark, dry and cool place like a closet, cellar or pantry. You can also use mesh bags instead of pantyhose. Onions stored in this manner remain dry and breathable increasing its shelf life up to 8 months.
