Satin stitch is my go-to filler stitch. I think this stitch is super sexy.

Sometimes I use it solo.

Sometimes I add an outline in backstitch (usually when my stitching isn’t exactly perfect and I want to cover up the mistakes) ;)

It’s a simple stitch to understand, it’s a bit of a beast to get good at.

Your goals with this stitch are: 

1. Zero space between your stitches (which usually means disregarding the holes and poking that needle right through the weave)

2. The front and back should look identical
