How to make a slip stitch (sl st)

The slip stitch (sl st) is one of the simplest crochet stitches and is often used to join rounds, create a smooth edge, or move the yarn from one point to another without adding height to the work. Here's a detailed guide on how to make a slip stitch in crochet:

Steps:

Step 1: Insert the Hook

Insert your crochet hook into the stitch or space where you want to make the slip stitch.

Insert the hook from front to back into the desired stitch or space.

Step 2: Yarn Over and Pull Through

Yarn over (YO) the hook by bringing the yarn from the back to the front, and then pull that yarn through the stitch or space and the loop on the hook.

Yarn over (YO) from back to front.
Pull the yarn through the stitch or space and the loop on the hook.

Step 3: Complete the Slip Stitch

You should now have just one loop on your hook, completing the slip stitch.

Step 4: Repeat (if necessary)

If you need to make more slip stitches, simply insert the hook into the next stitch or space, yarn over, and pull through the stitch and the loop on the hook.

Tips:

Slip stitches are often used to join rounds in circular projects, so pay attention to the pattern instructions if you're working in the round.
Slip stitches don't add height to the work, so they are useful for creating a smooth transition or for creating a decorative edge.

The slip stitch is a fundamental crochet stitch that's easy to learn and is used in a variety of crochet projects. Whether you're creating a simple scarf or a more intricate piece, slip stitches will likely be part of your crochet repertoire.
