Interlocking Floss Stitch Monogram comes in 2", 3", 4" & 5" heights. All sizes included in purchase price. Each size includes 26 full-height center position letters and 26 4/5th-height side position letters for making traditional 3-letter step-down interlocking monograms. The middle letters feature extra loops at all four corners for overlapping with the side letters for an interlocked look. All characters in all sizes are finished in Floss Stitch which stitches out on all embroidery machines using standard embroidery thread. JUMP STITCHES:This set intentionally uses long jump stitches between the stitch parts rather than connection stitches....connection stitches under such a narrow stitch would tend to "peek out" from under the finish Floss Stitch line if you have even the slightest amount of fabric pull during the stitch out. The jumps are long to make it easier to pick out and trim. The DST format files include trim codes for machines that read auto-thread-trim codes.
