If you need a little help with the sewing this visual aid will help - originally done for the knitting needle tidies but the corners are equally applicable here: HOW TO MAKE TIDIESThese napkins are very small and have tiny corners so I suggest that you thumb nail press first, then pin, then press. Keep the pin in the corner, start to sew from half way along one side of the napkin. When you get to the corner - keep the needle in the corner, lift the foot and pivot/turn the fabric. remove the pin and stick it in the corner fold - this will stop the tiny corner from disappearing down the plate hole when you commence sewing the next side.
