Polyfilla on a Jumper - !?

[poodlepusher]

I've been filling cracks in the walls all morning and not noticed I splotched two bits on my jumper - too late to wipe / rinse off.

Jumper is cheap old thing only polycotton but I wear it all the time coz it hides my recently deflated baby bump.

Any suggestions? (on jumper, not alternate means of concealing gut...)

let it dry and chip it off ! or it should dissolve in warm water

I've started wearing it inside out
