Has anyone had to stop painting in the middle of a piece?  I'm going to presume that knowing how to paint with Bob's wet on wet technique is going to be completely different if a painting is semi dry or even tacky.  

I'm looking for tips... I started a painting yesterday and had to stop suddenly.  It's 90% finished but there are glaring details that should have been added and I quite honestly don't know if I can finish it without screwing it up.

When a painting is wet, you could always scrape off a mistake and have another go at it... but now that it's drying, that's not an option.  I would love to hear your experiences, tips and thoughts! 

Thanks so much,

Darlene
