The Lace pattern makes this poncho very light and breezy. The poncho is one size fits all. I used Cotton Fine yarn by Brown Sheep Company, 1.75oz/50g skeins, each 215yd/202m (80% Pima Cotton, 20% Merino Wool) in Mink Brown color, but you could use any sport weight of finer yarn to knit this poncho. To make it you will need to know how to knit stitch through the back loop and how to knit 2 stitches together. Also the pattern has detailed photos to explain some of the stitches in it. The pattern has a stitch chart and a written description for each round. If you will have any questions, please feel free to contact me.
