LOL, SuziE - sounds like your DH and mine think veeeery much along the same lines!  I found myself painting the interior of a house during this pregnancy (oh not OURS, no, that's still got lovely plaster walls!  Ha ha).  And those little black bugs - what is up with that?!?  I thought insects should hate the smell of paint, but noooo. 

Using acrylic paint seemed OK to me.  But I did have trouble with working looking up, hands up in the air pushing the roller high up the wall - didn't go down well with being up the duff... I was soon seeing stars (and as it turned out, NOT seeing the bubbles I'd left in the paint because those lovely pretty stars were getting in the way!) and did a pretty, ahem... unique job of it!  I quickly got to the point where I refused to climb a ladder to do the top edges (having recently fallen over nothing - oh how embarrassing!) or crouch low to do the very bottom ones.  So Frantic, I say good on you for getting the whole room done - go you good thing, go!
