Fold in half the OPENING CUFF and begin pinning starting at one of the lower leg opening seam allowances, Ret mod ret. Ease the OPENING CUFF around.
TIP: fold the end seam allowances of the OPENING CUFF inside itself before pinning to hide the raw edge, or pin it to curve off the edge of the leg seam allowance to give it a rounded edge.
If you are using the HOOD, pin the OPENING CUFF from lower leg to lower leg going around the HOOD edge.
If you are not using the HOOD, simply continue the OPENING CUFF around the neckline and back down to the lower leg. Curve the OPENING CUFF at the neckline point instead of trying to get it into the angle.
Finish the seam allowance using zig zag stitch or an overlocker stitch.
