This Sew Clever's original designed easy reference Card Slot Guide is a so easy and fast method to fold and sew the card slot placements that are required from the pattern.
Simply place the template over the WS of fabric, line up and draw in the slots to reference the fold and sew lines with your preferred marking tool. No flip or turning of the template required, no additional ruler sides to line up, simply place on top of your fabric (interfacing side up) and draw the lines accurately once. The lines that require the stitching for the card slots are clearly marked.
A real timesaver with all the measuring calculated for you.
