- A language barrier, not sure how you'd do it in clay though. - a sort of barrier in love, my friends doing some sort of beauty and the beast thing, but romeo and juliet, that story about the swan who becomes a princess at night or something, shrek and beth and reese (incest) out of hollyoaks could work. just some ideas friends have had for theres. I reckon choosing clay is limiting yourself a bit though. unless your Reallly good at it i doubt i ll end up looking too good.
