I am desperate for help. I really want to make some of these and I have no idea where to start. They belong to my mom and were handmade and given to her as a gift in the 80’s. They go over Christmas lights. It’s a 3D cage.

I have the beads I think I need, but what kind of stitches or patterns do I need to look up? I’m so lost. I don’t have one in front of me to reference as I work, so I’m going off of this reference photo for now.
