Worked Filet crochet in F hook.

Had trouble with last (3rd) row of dc in edging being floppy and curling. Redid 3rd row of arm and neck edging in crochet hook two sizes smaller (D in my case). Also, on last round of neck decreased (dc2tog) 2 sts on back neck, 4 stitches on front neck and a stitch at each shoulder in addition to using the smaller hook.
