Collaboration

I've been taking a stall at the new monthly Arts&Crafts market in Croydon and one of the other stallholders, Tim from Seldsdon Ceramics, very kindly gave me a pot to 'draw' on.  I've never done this before so had no idea how to do it or how it would turn out!

I scratched lines with a knife but the areas which worked best were where I removed blocks of the covering 'slip'.  He's given me another one to work on, although I'm not sure quite what to put on it.  Any suggestions?
