Elf house on a tree! That would be cute in the garden, especially in the tree over grown with ivy. How about some battery tea lights in the windows during outdoor parties. I hear the fairies/elves whispering "home school project" in my ear.
Wall Trellis Kit : Use silicone glue to bond a number of anchors to a wall or window. Next, string the wire from anchor to anchor to create a frame. Finally, use the vinyl tape to support plants on the newly created trellis.
