Unicorn body pillow June 26, 2015 I decided to show you the process of how I made a body pillow in Unicorn shape. First draft your unicorn in actual size, with 2 inches outside for trimming and sewing. cut out all the fabrics and ready to sew! ready for stuffing remember to sew the horn, eyes and ears BEFORE you sew the body. detail shots. Viva, my own unicorn to hug to have rainbow dreams.
