A quick paint job!!! Not!!!

I decided that my guest room needed a quick freshen up. So I went and chose a warm 'off white' colour, ironically called 'Timeless(!)'

The problem has been that the colour I've been painting over was mustard yellow!!!! Yuk!!

As a result, a quick paint job of the smallish spare room has taken 4 pots of 'Timeless' paint instead of 1 AND two days of my life have been absorbed in applying and re-applying, time and time again, layers of paint to get rid of the yellow!! Aaaagghhhh!!!

I'm hoping today in the daylight the walls are now white with no mustard yellow seeping through!!!! Fingers crossed!! :-/
