Journey of this join: I was trying different join from single crochet, slip stitch in both loops or inside loops slip stitch. For these three joins, For me , I like the look of the slip stitch inside loops but its holey when stretch(my opinion only). Then sewing method came to mind. I was searching sewing stitches then embroidery stitch called Cable plait stitch showed up. It looks so neat. I was excited trying it using tapestry needle but ended cutting the yarn because It didn't work(was hard to rip it off and re done it). Then I was focusing on just using a crochet hook only because it's easy to rip it off when you get mistake & I used the cable plait stitch as an inspiration. After trying several times inserting hook in different loops: Zigzag slip stitch join finally made. And I am happy to share. Thank you so much.
