All about the needle join

SS/NJ comparison

The invisible join, which I call the needle join after Serendipity Crochet, is an alternative to slip stitching at the end of a round. I first encountered it on futuregirl’s blog; it’s fairly novel to a lot of crocheters, but it does seem to be a time-worn technique for finishing granny squares and similar items. What I want to add to the conversation is about using the needle join versus the slip stitch to smooth the edge of a crochet piece made in a spiral with single crochet. First let’s review how to close a round of double crochet with a needle join (or you can jump past).

Verbally: finish your last stitch, cut the yarn, and pull it through the stitch as usual. Thread it onto a needle and insert the needle into the first “real” stitch (not the turning chain) the way you would insert your hook to crochet into that stitch. Pull through and then insert the needle down through the top of the last stitch of the round. Tighten the teardrop to match the rest of the stitches (sometimes this requires pulling on parts of the yarn with your fingers) and secure the yarn as usual.

Now to compare this with slip stitch for single crochet made in a spiral. The main drawback of spiral crochet is the fact that the end of a round is a full stitch up from the beginning, so pieces with open edges have a significant height jog. Slip stitches are often used to mitigate it, and needle join suggested as an alternative. I have a tweak to the needle join option [spoiler: make a needle join in the second stitch of the last round.] – let’s look.

1. Slip stitch into next stitch (leftmost sample of top picture).

Pro: quick and easy.

Con: teardrop of stitch wants to roll to the front of the work; single strand emerging from top disrupts interlocked teardrop edge; can be problematic if you need a particular stitch count.

Best for: edges that will be invisible, such as those sewn onto another piece of crochet.

2. Needle join in next stitch (middle sample of top picture).

Pro: cleaner than slip stitch.

Con: extra work; makes a steep ramp between the round ends; can be problematic if you need a particular stitch count.

Best for: not much, IMHO.

3. Needle join in the stitch after next (rightmost sample in top picture).

Only two pictures this time because the edge-on view is essentially identical to the previous needle join.

Pro: cleaner than slip stitch; makes a gentle slope between the levels of the round ends; doesn’t add to the stitch count.

Con: extra work.

Best for: exposed round ends, such as on a disk or cup. I believe this gives the smoothest possible edge to spiral crochet.
