emagineer, I don't know how else to answer you
There wasn't an email in your post.
Yes, you can use the words. Which ones, the Possum Trot or the General Store? I just made the stencil on Word and enlarged it to 400 using Copperplate Gothic in bold, I think. I just looked to see if I kept the document so I could send it to you, but I just printed it & didn't save it.
I had just read that method of aging wood, but it said to use a steel wood pad and dark vinegar, let sit overnight, and then paint it on. I thought I might try that since it wouldn't cause the wood to shrink the way the baking soda did. But now after it's been up this long, and after the cool weather and recent rain, I'm not as afraid of the windows cracking. It was probably 105F when I tried aging it the first time.
