Thnak u If you build the mini one, it's very easy, the normal one is also easy, but I cant' tell for sure, because I haven't buil it. Do yopu have young child at home? If you do, I'd not suggest hanging on the ceiling XD They can destroy, as it's made of paper XD
I have a 2 year old that comes and visits once and a while. And she likes to get her hands on everything. But the ceilings in my house are pretty high. I can't reach it, not even by jumping. I'm not that tall as it is, but if I can't, then a two year old can't.
iy's kind weird: i printed a piece of page into black. than i cutted the two slices. whit the slices, i cutted wire in the size of the side of a page. i got the slices and glues on the wire. than i just molded it in the way i wanted. i dunno if u understood.i think that the thicker paper wont hold it.
