I love Halowe'en and all thing spooky, this wicked witch stands at 4 inches tall if gauge is met but as gauge is not really important try making her with super bulky yarn to get a bigger fright.
I used 4mm pearl beads for her eyes and crocheted them in as I worked but sewing eyes on/in would work just as well,

I crochet, it's what I do, stitch follows stitch follows stitch.
I teach crochet, write patterns, experiment with styles.
