This looked so amazing but I was massively disappointed! Very fiddly to put together, one of the planets wouldnt open at all, and one was torn inside. The strings/wires also weren't strong enough to hold it up and kept falling down even though there were two less planets on it and we tried all sorts of ways to secure it. I didn't even bother stringing the letters up as the planets were such a nightmare! We followed the picture as there were no instructions, but I think it would work much better if you pinned the planets individually to the ceiling or had your own stronger string/fishing wire etc
