Her gown features a sequined bodice.
Her matching cape has a sequined collar.
As you can see the set was made using size 10 crochet thread. The addition of the sequins make an otherwise simple dress & cape into something spectacular.
To work with sequins you must thread them onto your crochet thread. Then before you finish a stitch that requires a sequin you first slide the sequin as close to the hook as you can, yo and finish your stitch!
Enjoy!
