All I can say is WOW! Sorry for being late to comment on your completed project. It really is amazing and might be something that I can make in the future as converting detolfs isn't really a viable option for me because of space.
Thank you so much Kiki, for the detailed instructions and clear photographs, I'm sure plenty of people will find them useful.
I know I won't look at my lack table that I have for my tv, in quite the same way again.
Even though I'm exhausted due to having been woken by my upstairs neighbour and guests at 2:30am and haven't been able to get back to sleep due to their continued noise making, nearly 3hrs later, my brain is chugging away with wonderous thoughts of lack table conversions!
Congratulations, Kiki and thanks again for posting so clearly.
