-D-E- 🤣 If you can open up my brain, you can have plans for many things!
I used to have a woodworking business, and had to design many items for a company out of Seattle. He would tell me over the phone what he wanted, and I would build it. We did this for several years, yet there was never 1 drawing for anything I made. Even the jewelry boxes I designed/built. I always said if I cannot see it in my mind, I can't build it. So, any plans are, seemingly, locked away.
