Hello, I've never gesso'd a canvas before, and unfortunately the process is king of owning me...first off, I get ridges. No matter how many layers I apply and passes I do with the credit card, every time I try to rid of a ridge I make new ones. What can I do about this? Let it dry and sand it down a bit? Just use a huge squeegee the size of the whole canvas? Also, when it dries it buckles out a bit...not so much I can't use it as a painting surface, but would be nice to avoid this if possible. Is there a solution? Thanks, looking forward to the rest of the course

I just rewatched all the feet videos and missed this the first time around...apparently this robo-foot model is posable? How do you do that? I can't find any kind of controls that seem to offer that option
