I am a bit puzzled on the subject of stretcher bars.
When you make a canvas from stretcher bars and canvas (rather than buying ready-to-paint stretched and treated canvases), what is meant to happen when you finish your painting, and say you want to put a frame around it. And maybe hang it on a wall, something like that?
I just glimpsed at a Youtube vid on this subject and the idea seemed to be that you don’t in fact remove the canvas from the stretcher bars. Instead, you slot it into the frame and then attach it will clips, apply various preservative materials, etc.
My question then is: is this the normal, time-honoured approach? It’s just that stretcher bars are a little pricey, and I had assumed they were probably re-usable items, rather than consumables. Maybe I need to try making them...
No doubt there is a rationale for this, i.e. if you remove a stretched canvas from its stretchers it’s going to go all floppy (the most obvious explanation I can imagine!).
