El tejido es con dos agujas, pero las imágenes dan una buena idea para hacer un bolero con un rectángulo. Yeah, that's what I was gonna say. actually this can be done knitting, crochet, material as it is just a rectangle sewn to make sleeves!
Gypsy Dolman Top:“This crocheted side-to-side pullover is super easy to make - two unshaped rectangles are seamed at the top and bottom and left open in the center, making openings for the head and torso. Pattern available from KnitScene Winter 2008
