Oh my goodness, how clever is this?! Put your harvest of onions into the nylon leg of re-purposed pantyhose, tying a knot after each one that’s added, and hang in a cool dark place such as your basement or under the stairs. Simply use scissors to cut off each onion section as you require, and enjoy your bounty through much of the winter. Smart!
