Instead of crocheting the pendant, you can cut out a circle of felt. See Anna’s felt pendant in the colour burgundy.
Ch chain stitch
Ss slip stitch
Dc double crochet stitch
Start by making a magic circle with 6 dc.
Row 1: (2 dc in next s) x 6 .
Row 2: (1 dc, 2 dc in next s) x 6 .
Row 3: (1 dc, 2 dc in next dc, 1 dc) x 6 
Finish with a slip stitch, and hide both yarn tails.
1. Cut the chain to the desired length. Attach the clasp to the chain.
2. Using the flat-nose pliers, now open the O-ring and attach the crocheted charm you have just made, as well as a metal pendant of your choice. Remember to insert the chain through the O-ring before closing the O-ring using the flat-nose pliers.
You have now made a piece of jewellery for yourself or one of your loved ones.
