In answer to your question: Very carefully.
I use a combination of storage methods. I hang some (usually the large, nice, or very $$$ ones), I use a pegboard for most of my small electrics, Ceiling racks in the garage for .20-.60 glo fuse&wings, and a seperate wing rack floor to ceiling made from adjustable metal bookshelf brackets and foam tube. Foamies are tough because they seem to attract hangar rash very easily. Consider storing them where you have to use the least amount of effort to get them.
I also take over the floor of the spare bed room for building during the hotter parts of the summer, so several planes live there too, on a temporary basis. Drives my wife absolutely nuts, even if she won't admit it.
