Door Jamb solution
Tried the Door Jamb Span the other day with my two kids. Here's a shot of their solution. There was initial trouble as they discovered that the labels wouldn't stick to the bare wood of the door jamb, but they problem solved and connected their span on one side to the metallic parts of the doorway.
I hadn't planned for the labels to be a problem, and I could have stepped in and changed doorways. Instead, given a little time to think, they figured it out on their own. This is a valuable lesson for leaders to learn – trust the team to figure out a workaround!
