That's the one I used. The only thing I did differently was to box the corners so that the tissue packet fit better and the corners didn't stick out. I turned the tissue cover inside out, flattened a corner, making sure the seam line is in the center, measured up about 1/2 inch from the point and stitched across the flattened corner at that 1/2 inch point. Box the other three corners, turn the cover right side out, insert the tissue packet and you're done.
