I think for a cushion, I might use a slightly larger seam as in regular garment sewing. That would be a 5/8 inch seam. I might start out by cutting the square out an inch or so bigger than the cushion, but you might have to adjust a bit when you see how it fits. You can always baste with a larger stitch, then try it, and sew again with a regular stitch. If you want it to be removable, you can either put a zipper in the back or you can make an envelope back so the cushion cover will slip off for washing. You should be able to find instructions for that on the internet if you search for maybe envelope back for pillow or something. Good luck!
