Since I like doing everything the hard way yesterday I decided to re-tissue Booty's windows (as the sun is so bright in her room) without testing the paint I used on the white tissue paper. When it was dried the white paint looked like mud after I held it up to the light. I had to redo all of the panels.

Materials:
White trace paper and colored tissue paper with white acrylic paint mixed with water.
The Dr.Ph.Martin's brand looked muddy so then I used another brand and tested it first.
Method:
Tearing pieces and overlapping them with bleeding and/or non-bleeding tissue paper (depends on the effect you want)using watery white acrylic paint and then more white trace over the top to give a misty look (or not if you want it more stained glass looking).
I hung a wool batting angel over the side because that is where Booty sleeps.

In two other windows I made obscure castle shapes or whatever you make of them.
