My Sierra embroidery software shows I can use two color block at 2.56" tall. I typed in the name HOLBROOK at 1.76" tall. The screen shows stitches missing (not filled) and when I stitch the name the stitches are missing (varied, spotty, not filled correctly) What is wrong? It defaults to satin which is what I want; changing to a fill stitch would be too many stitches. I shouldn't have to change this to a fill stitch when the parameters indicate 2.56".
