This snug-fitting cloche style hat is finished with a butterfly button which gives the hat its name.

Starting with a loose-ish cast on, the hat is knit sideways using short row wedges. The twisted stitch cable band is edged with two cables whilst the crown of the hat is worked in short row garter stitch. After sufficient repeats of the cable pattern and short row wedges, the garter stitch bind off is sewn together with the garter stitch cast on. If you prefer a seamless edge, you could cast on with a provisional cast on and graft together with the live stitches. The brim then decreases in pattern into a point which is secured to the brim with a button.

Dealán Dé (pronounced Dee Ah Lawn Jay) is an old Gaelic word for butterfly although directly translates as God’s lightning.
