Yes, they can be used. You may also want to look for a color wheel to go with it. When the aluminum trees came out they also had a wheel that rotated with different colors on the tree. Nothing can catch fire on these trees and they are very "modern" in their way.
A good selection of retro Christmas stockings can be found on Etsy, the handmade crafting and vintage auction site. Of course, if you cannot find what you are looking for there, then Ebay also stocks a wide range.
