I have a old desk from my hospital. It is a heavy (metal) and it is 1.75m x 0,80 m deep.
It is easy to clean and alot of room to put some things on (i mean there is alot off stuff that i don't use when i'm painting).
Beside the large deskroom, i have 4 drawers in. So when i bought a new figure, sneaked it in, i save it in there so the misses cannot complain.
To sit when i'm paiinting i have a chair on wheels (old bureauchair)
So go for it.
