SATIN STITCH

Satin stitch is the standard fill for letters and narrow design elements. The machine stitches back-and-forth across the column, packing threads next to each other so the result reads as a single ribbon. Satin works well in columns between roughly 1 mm and 8 mm wide; outside that range, density errors and thread breaks become common.

Letters and outlines stand or fall on satin quality. Too narrow and the needle perforates the fabric; too wide and the satin loses tension and snags during wear.
