Forgive me if this question has come up on this forum before as I haven't posted to this forum in many years. This is a question for those of you with ample experience stretching this kind of portrait linen canvas. Only Claessen's #13 does this to me.
The problem is the rippling on the edge in the photo, a canvas stretching issue, and it is driving me nuts. I don't know that Mark has talked about this specific issue directly but I was hoping someone could help me understand it. I "believe" I am following his video to the letter...
Do I need to invest in higher quality stretcher bars, with well-built bracing, for this brand of linen?
What am I doing wrong to cause my stretching to come up weak or uneven like this. What do I need to focus on when I am building my canvases to avoid this problem? No one has ever talked about corner keys, would that help this? I don't know how they work.
I thought about making some kind of corner bracing, or corner wedges, maybe learning more about keys to tighten the stretchers.... everyone I have talked to is dismissive of corner keys so no one ever teaches how to use them. Do any of you out there have any ideas?
