A safe house for butterflies. Holes are designed so they fit in, but their predators (birds) don't. In the back wall there are holes for hanging.
The house itself does not require glue, but I have added some butterflies in the file and you can glue those on the house. Also 1 big butterfly that has 2 parts, paint the bottom part with some nice colorful paint and then glue the other part on top of it.
