Doll stand behind the scenes

I love seeing others' photo set ups, so when I started using an invisible doll stand I thought I'd add pictures.

First I posed the doll. Then I tied fishing line to a large straight pin and stuck it into the doll's head. I held the line to my rig with tape. The tape held sufficiently long for photos, but I returned later and dolls had fallen.

I have no idea what my rig origins were, but it is a sturdy piece of metal tubing, formed in this shape when I came across it. I only showed the right side of the rig, the left is the same.

Thank you to everyone who has previously posted photos like this for providing so much inspiration!
