These things are super easy to make. I decided to cut my neck line in a u instead of the V neck. The sizing of the ready to ware ruana's were 59"x44". I used their measurements to construct my ruana. I feel like my ruana was not long enough for my 5"3 frame. So If you decide to make one use your tape measure.
I purchased 2 yards of fabric. Ponte what else? I have about 1/2 yard left, so it only took 1 1/2 yds.
All I can tell you is, come October, my sewing room is going to be like a factory. Every female in my family will get one of theses for Christmas. Even the kids.
We are going to a concert this weekend this one will really come in handy with the LBD I am wearing.
