Am painting my windows for halloween party what paint should I use

[twinsetandpearls]

Have poster paint, water colour pallete and glass paints. Worried about washing glass paint off.

I wouldn't use glass paint...that doesn't wash off. Poster paint should do it.

what I thought thanks

If it doesn't 'take' onto the glass properly, try mixing a little PVA glue with it.

Thanks mrsmaidamess great advice. Will post a pictre
