Fill Stitch designs are exactly what you think they are . That is , they are machine embroidery designs which aim to achieve overall stitch cover. You might call them classic or traditional embroidery designs.
We classify them this way in order to distinguish them from other types of designs , like Open Stitch and Applique.
Generally speaking , our fill stitch designs are just dense enough to avoid base fabric show through. But not so dense as to cause problems on lighter weight knits and sport materials.
If you are wanting a design to stitch on a particularly demanding fabric, just give us a shout. We are always happy to adjust density , or any other parameter , to your specific needs. Of course, at no additional charge!
