Wah, Wah! Bye, bye, Old Billy!
Someone posted on the IKEA thread that the old Billy doors wouldn't fit the new ones.
They are changing the Billy! It will now be deeper, in order to accommodate items other than books. :(
Part of the Billy appeal for me is that it is narrow. Fits in so nicely into spaces and makes it look more like a built-in.
I always meant to buy extensions for mine. Kept putting it off. And now, out of stock locally, out of stock online. Very disappointed!
