Our Guild had a program, then a workshop on making them. Some of our members were not happy with theirs. I love mine. I have 2 garage doors and have mine hanging above and between them - centered from the peak. The wood she brought to use was probably thinner than it should have been because many of them warped. I ended up framing mine because I had a problem with how to hang it. She advised us not to use a sealer because the paint was left over house paint and would hold up to the weather. I've had mine up for 5 years with no problem (except blowing off in a big wind storm) It identifies my house!!
