I think yours is the best tutorial I've seen on creating a big board. Can I ask - what is the layer of aluminum foil for? Carrie on the Prairie (www.carrieontheprairie.com)
Carrie, the aluminum foil is to protect the wood from steam. I use a lot of steam and I didn't want that to warp the wood.
I have also taken the board alone to a group sewing session. After setting up tables far enough apart so that each of the ends rest on a different table (nothing underneath it) it provides a LARGE legless ironing area. Sure was popular.
This looks fantastic, thanks for the great pictures and your helpful tips.
