Kristin and I must be kindred. I have the same hoop and make the same knots. But, I made muslin sleeves to go over 2 sides of the frame so I could pin the quilt to the muslin whether it be the side or the corner. The corner was even harder. Put the 2 sleeves on 2 adjoining sides of the square PVC hoop and pin the corner of the quilt to the muslin sleeves. So much easier to quilt that way.
