So, I guess it's an age old problem. Apparently something about lead not being good for us and that making gloss yellow... 
But on a more serious note, what is the best solution. I painted the walls in white silk, they still look lovely and white. The gloss is a dark cream and it's sooo frustrating.
What is the best solution?
Do I have to sand back to wood, prime, paint etc. again?
Is gloss these days just shit, and is it worth considering a silk on them?
