Vision board on a string? Not sure if this seems too messy, but I still like it as an improv for not having an actual board yet.
For many creative people, having a place to hang up images and ideas in real life rather than keeping everything online is a must, but hanging a cork board is not always ideal. Putting up a cork board can be damaging to a wall and when it it is time to change things around, it can be a pain to move....
