Craft Window Painting

For a few years I worked for Wal**** and the assistant manager Steve discovered that I could paint promotional items on windows that were not permanent. These pictures are from those years (2003-2004). In general artwork like this only stays up for a month or so. The grand opening however stayed up 2 months before it was changed for the halloween window. Season's Greetings was up from Nov 5 until Jan.
Prices for 'window art' is according to the following: 1- is the art painted on the outside so that the work is 'positive'? If not the entire painting is done in reverse from the inside of the window. Reverse painting takes more time. 2-how detailed is the project. 3- conditions during painting (this includes weather, crowds and ladder work.

I require a clean window to paint on and objects cleared away from the work area. My paint mix is acrylic with an additive that allows you to remove a painting later. The paint does stick rather well and generally can take indirect rain without dislodging. To remove the paint it takes a great deal of water and a green scrub mat (think dishes) to remove the stubborn or thick spots. If the painting is outside the artwork will come off with a power-washer fairly easily. My additive foams up- but is nontoxic.
A good rule of thumb is: A- simple, positive painting is $2 a square foot. B- complex. positive painting is $3 a square foot. C-simple, reverse painting is $4 a square foot. D. complex, reverse painting is $6 a square foot.
