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!
Crochet in Color: Lots of Free patterns. I always go with the smallest hook for baskets, bins, etc. More useful if you don't have to shape them. The only time I use a bigger hook is if slouchy is what the design calls for. Make Crocheted Baskets!
