I have one sitting in a corner because the quilt catchs on the edges when you try to quilt it.
So I ended up buying a sewing table that has a lift in it and lots of counter around it, what a difference it has made.
Dont settle for less than a large flat surface.
Those videos of foam flat surface looks like a great idea and you wont be out a hundred bucks for something that does not work. I speak from expierience.
