I came across this item while looking for a stand to hang a witch ball from.  I own many Umbra products and while the price was a bit high (compared to others) I bought it.  It is a bit light but it feels like you could remove the felt from the bottom and fill it with lead shot.  Until I can get around to buying some, I tried hanging the 6" diameter blown glass ball from the tree with fishing line.  The stand did not falter.  To give it a little more safety for now, I placed some river rocks on the leaf to help weigh it down.  It works like a charm.

If you are buying this just to hang jewelry, it will hold a lot.
