Painting pyramids work well for larger projects, but when you have smaller items to spray, something on a smaller scale is needed. I took a piece of corrugated cardboard and inserted tacks in it from the bottom. I spaced them about an inch apart and covered the flat sides with tape to help hold them in. The item you want to spray is held up by the points of the ‘thumb’ tacks so that it won’t stick to whatever it’s resting on.
[EDIT] I just found a few more pictures from earlier in the process:
