Appliqué Satin Width and Density Guide

Updated October 15, 2026 · 5 min read

Two settings change how an appliqué edge looks more than any other: how wide the satin cover is, and how closely its stitches are packed. Here is what each one does and how to pick values you can trust.

Satin cover width

The satin cover is the visible border around the fabric. Wider covers look bolder and hide the raw edge more safely; narrower ones look finer. In the appliqué tool the satin cover thickness runs from 1 mm to 8 mm, and the default is 2.5 mm.

  • Around 2.5 to 3 mm is a common, neat edge for letters about 2 to 3 inches tall.
  • 3.5 to 4 mm gives a bolder look and more forgiveness if the fabric shifts slightly, but needs thicker letter strokes (see fonts for appliqué).
  • Wider than 5 mm suits large letters and puff styles. At this width, satin stitches get long; see the split satin note below.

Satin density

Density is the distance between satin stitches. The tool’s range is 0.2 to 3 mm, with 0.4 mm as the recommended default. Smaller numbers pack the thread tighter and look fuller; very small numbers risk puckering and thread build-up. Larger numbers sew faster but leave visible gaps between stitches.

Tip: Keep the recommended 0.4 mm unless you have a reason to change it. If your fabric shows through the satin, try a slightly smaller number rather than a much smaller one.

Tack-down width

When the tack-down is a zigzag, its thickness sets how wide the zigzag is. It must stay at or below the satin cover width, otherwise the hidden guide layer would show past the finished edge. A narrower tack-down holds tight corners and small counters more cleanly; a wider one gives the satin more foundation on soft or stretchy fabric. If you choose a running-stitch tack-down instead, there is no width to set. See zigzag vs running tack-down.

Fabric type and pull compensation

Dense stitching pulls fabric in, so the finished satin can come out narrower than designed. The Fabric type setting adds allowance to the placement, tack-down and satin to compensate.

Split satin stitches on wide columns

By default, satin stitches longer than 6 mm are split in two, which can leave a faint line of small dips down the middle of a wide satin column. The Split satin stitches checkbox turns that off, so every stitch runs straight across. That gives a cleaner column on wide covers, with the trade-off of longer stitches. A stitch file also cannot hold a single stitch longer than about 12 mm, so very wide columns are still split where needed.
