The slip stitch is also often referred to as a ladder stitch or invisible stitch.
The slip stitch is used to close pillows, linings, stuffed animals, and more.
The slip stitch comes up again and again in sewing regardless if you are making bags, plush toys or garments. Being handy with a slip stitch is extremely useful.
When you slip stitch you are usually joining or closing two folds.
We make our stitches parallel to the folds, essentially hiding the thread inside.
Your stitches often begin to look like the rungs of a ladder, hence the name.
Once you pull the thread, the layers will join making the stitching invisible.
It helps when slip stitching if you use a thin sharp needle. I also like to double thread my needle so I don’t have to worry about it sliding off.
