Free Crochet Tutorial – Surface Slip Stitch Join

Oct 22, 2021

I’m so excited to share with you this free crochet tutorial for working a surface slip stitch join! I must confess that finishing details are not my favorite part of crocheting. In fact, I have been known to work my designs in such a way to reduce the number of ends that need to be woven in! While finishing details still aren’t my favorite, I do love the surface slip stitch join. It is a beautiful and sometimes seamless looking way to join two pieces of fabric together.

Tutorial Details

For this tutorial I’m using Brava Worsted Weight yarn in the colorway Silver. This is a great yarn for practicing stitches. It is sturdy enough to show great stitch definition, but soft and flexible enough to glide easily through the hook. I’ve saved this skein just for practicing stitches and it has held up super well to lots of frogging! 


Whenever I’m practicing a new stitch, I like to use a hook that’s super comfortable in my hand. No sense fighting the hook while you’re perfecting your stitches. I love wooden hooks and the Furls Streamline hooks are a favorite and are priced fairly reasonably. For this tutorial I’m using one of my most beloved hooks, Furls Alpha Series. They are my absolute favorite and an extra special treat! For this tutorial, I used a US J-10 (6.0mm) hook.


Working a surface slip stitch join is a great way to seam almost any project together. Do keep in mind that the surface slip stitch join creates a raised slip stitch detail on the outside of the fabric. This can be a really beautiful addition to the seams of your pattern as long as that’s the look you’re going for! Read all seaming directions carefully when you’re working this stitch as part of a pattern.


Working the Surface Slip Stitch Join

The surface slip stitch join is worked through two sets of stitches. This can be done by working through the edge stitches of something like a granny square or seaming two pieces together or it can be used to join the beginning and end of the same piece. To join the two ends of the same piece, you must work into the back bump of the starting chain. If you’d like to learn how to work into back bump, you can find a tutorial here. If you’d like to seam pieces together that are worked back and forth using a surface slip stitch join, you can add single crochets or slip stitches around the edge to make it easier to join. To make sure your piece will lay flat, take the time to be consistent with your placement and work loosely so as not to bunch the fabric.

To practice, I recommend working through tops of stitches. To do this you can seam two granny squares, make a long piece starting by working into the back bump or working two pieces and seaming tops together. Since it’s just practice. I would go with whatever sounds easiest!
