Kyle- It depends on where you live. We assume you do not live in the south, since you are talking about planting onion sets in the spring. You should store the sets in much the same way you would onions. Put them in a mesh bag and hang in a cool place with good air circulation (not the basement). Check periodically throughout the winter for damage or rot. If you see damage or rot, remove it right away so it does not ruin the rest. Plant in the spring.
