With this pattern, you have many options:
You can string beads on and work them into the picots, or where ever you would like into the main body of the choker.
You can hang a charm or pendant from the center motif, or attach a charm or pendant to a small lobster claw clasp and clip to the center motif, then you can change the pendant with your moods.
You can also choose to make the crocheted ribbon that is included in the pattern, or use 1/8” satin ribbon instead.
Make the main choker piece in white or another neutral color, then make, or buy, different color ribbons to change out to match different outfits.
Gauge is not too important. Size is determined by the length of the ribbon.
Intermediate pattern because of some of the cluster stitches used in row 6
Optional: glass seed beads and pendant.
