For the base colors, get some cans of flat house paint,-(must be flat!), oil based is more durable but harder to cleanup. Just roll it on with a roller. For the details, feathers, cheak patches, est. cut out stensils out of cardboard. As for colors to use, use the real thing as a guide. Look at some photos of real geese or some pictures of commercial silos. What do you guys use for stakes? I have made some great lookin silos out of 1/4inch paneling but I can not figure out how to stake them up.
