This poncho pattern is called EMBRACE. The poncho is closed with snap fasteners along one side, so it EMBRACES you.
The following description in the English dictionary describes the Embrace Poncho very well:
EMBRACE: “To hold someone tightly with both arms to express love, liking, or sympathy, or when greeting or leaving someone” (Cambridge English Dictionary).

The poncho is worked back and forth in rows in one rectangular piece. It features an overall lace pattern framed by seed stitch side panels and a rib border at both ends.
With the buttons you can close the piece to wear in a slightly asymmetrical poncho shape - or drape it around your head and shoulders and button it in alternative ways for a different, modern look.

The poncho is one size and measures approx. 65 x 65 cm/26 x 26 in when folded in half and buttoned.
The pattern includes both written instructions and a chart for the lace pattern.

We worked our sample in just under 250 g of light fingering einrúm Lamb 2 yarn, an almost unspun merino wool plied together with an ultra fine strand of shiny mulberry silk for a unique and exclusive look.

We used 3 mm/US 2.5 needles for a tension of 3 lace pattern repeats measured horizontally = 10 cm/4 in and
1 lace pattern repeat measured vertically = 7 cm/2.75 in.

Stitch markers and a row counter will come in very handy when keeping track of the lace pattern.
