I took pictures of the process (and measured!). The measurements for both pieces of the fold are in the pictures. Tomorrow, I wil edit this post and try to write up directions that make sense. I'm sleepy (have I mentioned I have narcolepsy and chronic insomnia?). Anyway, I took my night meds and I need to sleep. I just don't want Lorri to have to wait to see. Here are the pictures. I will pretty it up tomorrow. Some of the pictures, you have to click to make them big enough to see the dimension information.
Thanks for letting me know Lorri!
