Note: I used a P (11.5 mm) hook (the 11.5 mm size is not listed in the choices above).This cocoon is quick and easy to make. Make as many rows and stitches you need to make the cocoon 18” long x 16” wide. I made a rectangle 23 rows of 32 HDC stitches in the 3rd bar. Video explaining stitch here: http://thelaughingwillow.blogspot.com/2010/11/surface-bra... Wrong sides out stitch the rectangle together from the bottom up about 4 to 6 stitches. The rest will be left open. Next, DC evenly around the bottom 3 Dc for every two rows. Next round DC 2 tog around, leave a long tail and weave around the stitches and pull tight to close circle. Tie off and weave in ends. Add buttons to close cocoon.
