The process actually creates a "false stitch" - this means it looks like there is a completed stitch rather than the join and it hides your end point. Follow these step-by-step photos and instructions to learn how you can use the Invisible Join to finish off your own crochet projects:
To work an Invisible Join, start by fastening off your yarn after working your final stitch - do not join! Using a yarn needle, work through the stitch you're joining to, pulling to tighten.
Bring the yarn back around to your last worked stitch and go down into the stitch from the top, creating what appears to be an actual stitch. Adjust yarn if necessary to make it blend in with other stitches. Weave in end.
