I unblocked myself by writing a short story about my tabletop character, which I thoroughly recommend.
I wrote it for four people, plus myself, so I'm unlikely to share it, but: two of those four have read it and loved it. Sometimes, success is finding the right target sized audience.
So there you go. Writing tipz™ from your pal C dot Finn.
(P.S. I may have briefly become the kind of lady who puts Jamie Paige lyrics in stories)
