My last contribution is an easel for photographing artwork. It will allow just about any framed art piece to be clamped between the two horizontal pieces, and at a variety of heights. In the photo I have an Ikea cork board mounted and I generally rest artwork on several small pins, some of which can be seen. A box of pins sits on the top right.

That thing on the upper left is just a bag of the bird feathers that I have been able to collect. I built this to photograph my mother's art that I sold after she passed away and I have found it to be quite handy since then. Note that this easel is very light construction and is fine for photography but if you want an easel for painting it would need to be a bit more sturdy than this. Pardon the floor as I am converting this room into a photo studio and the new floor is not yet installed
