Use an index card, put your needle into a line and then put tape to the right of the card, this is 1/4". Build up the tape if needed. Or take some post-it it notes (about 6, do not take apart)and place to the right of the card. Place the sticky part next to the card. Your fabrice will ride along the edge of the post-it note. For a scant quarter, move closer to the needle.
