Animal patterns for stained glass are really quite hard to do.  I was asked for a coyote in a custom pattern and hunted and found one i liked (a free pattern from Spectrum stained glass newsletter) but really didnt like the way the head of the coyote was shaped but did like the hind legs and tail.  I edited it and put it at the foreground of this desert sunrise pattern. pdf download, and i can edit the dimensions somewhat, just check out with the "customize my pattern" menu item, it does take time to edit these.

pdf download, letter size, vector black and white page enlargeable to whatever you want, just ask the printer (like staples or kinkofedex or any quick print store to enlarge it and print it on their large format printer in black and white)
