What you will need:
C/2.75mm crochet hook
4 - 1/2" plastic cabone rings
Embroidery floss in two colors
4 jump rings
2 - 9" pieces of 1.6mm sterling silver cable chain
Step 1—Crocheting Around the Rings: Insert crochet hook into plastic ring and pull up loop. This counts as your first stitch. 20 SC around plastic ring, making sure to crochet over beginning tail. Cut off beginning tail that has been crocheted over. Leave 3"–4" tail at end to weave in (see step 2). Make three in one color, and one in the other color.
|Crochet around ring and over tail.|
|Back side of crochet ring.|
|Front side of four rings with beginning tails trimmed and 3"-4" ending tails ready to weave in.|
Step 3—Attaching the Other Rings: Thread ending tail onto embroidery needle. Starting with the front facing you. Place needle from back to front through the first stitch (like above). Pull through and tighten. This time, place needle from front to middle of last stitch (see the picture below). Pull through and tighten.
Holding the finished ring you just made in Step 1 with front facing you, run the needle through the middle of 2 or 3 stitches (see first picture below). Pull through and tighten. Run needle through the middle of 2 or 3 stitches on other ring (see second picture below). Repeat a few times until they are securely attached. Knot off and run needle underneath crochet rings on back side to hide thread (like in Step 1). Trim end. Repeat for third and fourth ring to form crocheted ring chain.
Step 4—Making the Necklace: Attach jump rings through a stitch on each end. Attach chain and clasp...and you are done!
