The easy to read markings in red on the 1/4" Low Shank Little Foot markings on the front and back of the foot are invaluable for setting in the "dreaded" Y-Seams. In sewing hexagons e.g. Grandmother's Flower Garden; trust the foot markings start sewing at red 1/4" front mark and stop at red 1/4" back mark. Use this same method on any inset-seam. Works like a charm every time.
