Yup, was at Verns' for most of the day today putting the finishing touches on the boxes and finding out why the drawers stick.
Well actually we investigated that the other day and surmised the blasted things were sticking in the sound proofing I put in.
So I ripped out the sound proofing, easy fix - annoying though.
Have now bought the same as was originally in the back and will use that to cover the floor to ensure the drawers etc. don't rub and make annoying noises.
All that's needed to finish the side boxes now is a lick of paint.
Thanks Vern for all your help - I honestly thought I'd never see the day that I'd have drawers in the back! It's taken sooo long...
