I have a few times, but I only have one pic of the project to show. It is a spicy spiral. For a tree skirt, I am pretty sure you would want to press your seams open to help with the bulk and bulging in the middle. I know sometimes it is even best to use a 1/8th inch seam allowance if piecing narrow strips.
I used clear medical tape on the back of my ruler to keep it from slipping. It is removable if you wish too.
