This mobile came about because of my son. He wanted a hand made mobile by me for his room because his sister had one! So I thought and thought about what type of origami I could fold and would work on a mobile. When I gave him all the ideas, he liked the airplanes the best. So I set to work finding the right kind of paper and how best to attach them. He now has one in his room and I thought other boys might like them too! This mobile has 10 airplanes that are approx. 6 inches long and 1 inch thick. They have white ribbon glued on to hang them from the mobile kit. Each plane is attached at a different angle of flight. The airplanes are light and aerodynamic so they move with any slight breeze or change in air pressure. Total length of mobile is approx. 28" long and total width of the mobile is approx. 18". Metal mobile kit is 22"x16". I used a fun mix of traditional origami papers in shades and patterns of red, blue, green and yellow. Mobile has a loop on the top for easy hanging from a hook in the ceiling, so it can displayed over a crib or a changing table or anywhere really!! It can also be attached to a crib arm just let me know at purchase and I will modify the mobile to be used on a crib arm. This mobile and all the items in my shop come from a smoke free home and studio. ***There will be some variation in the origami paper used on each mobile because the pieces are handmade and placed, so please expect some variation from the picture.**** Inside display highly recommended. Not for outdoor use. This is not a toy. Please keep out of reach of children. Would you like an airplane mobile to match your room or nursery? I can make custom airplane mobile in colors to match your room colors or bedding colors.
