A frame in the artist's studio (5)
I believe the answer is:
easel
'a frame' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for easel that I've seen before include "Artist's tripod" , "Artistic tripod" , "Painter's tripod" , "Artist's canvas holder" , "Framework to hold a canvas" .)
