What advice would you give someone starting this project? Be sure your grainlines for both layers match perfectly to be sure you have sufficient stretch. If your grain is askew you lose the give and it may not fit. I suggest if you plan to make an embellished poncho, baste all the edges together and the one seam to check the fit. I would even suggest adding about 4 inches to the length which I think takes it to 58 inches.
