·	Cut apart the pattern and put back together like a puzzle. Cut away a quarter of an inch where you will be using masking tape to adhere to the window. Masking tape the sections around your first color.

IMPORTANT NOTE: It is not healthy to breath the paint mist in the air so wear a gas mask if you have one available. Otherwise, it is important to do this only with very good ventilation. We opened up the room fully and wore top quality dust masks (these do not really help much, so don’t rely on them to make it safe.) Between color applications we put on fans to pull the mist out of the room, and took a half hour break away from the painted area. I would not advise a person with any kind of breathing condition do this without a gas mask.

·	Practice spray strokes before doing them on the window. Use long strokes or circles for more texturing. You will want to start each stream of spray on the masked part and then move onto the window to keep a steady stream which avoids any big blotches.

Spray one section at a time on the back side of the window (You want to see the paint through the glass). The side you paint will look painted. The other side however gives the illusion of stained glass since you are seeing the color through glass. Experiment if you like on a piece of glass or an old jar to get the idea.

·	Let each section dry (it doesn’t take too long, but don’t rush it since your paper will stick to the paint and peel off your work if you do it too soon.)

·	When all colors have been applied you will have some flaws or gaps between colors. This will be no problem since the black paint will cover those areas anyway.
