Are you having trouble getting those scant 1/4" seams?Yes, a quilter's foot for your machine is great, but can be expensive. I have tried using painter's tape, masking tape, sticky notes (stacked up) and mole skin. Nothing was satisfactory to me. The tapes came off too easily (when I didn't want them to), the grandkids had too much fun with the sticky notes and the mole skin wouldn't come off! :-/
One of our customers told me of this neat trick.
The only thing you need is a lined index card and a sewing machine that the needle will change positions.
Line up the side of the presser foot with a line on the index card. Now, start sewing. Move your needle position so it is just barely to the right of the line. Wah La! You now have sewn a scant 1/4". Just make sure you record exactly which position you needle is in for future use.
