Kristin, I'm not sure how this is going to work out in the end. I'm going to attach a photo that is a similar pillow. It's NOT the one I'm stitching, but it seems to be basically the same idea.
Although now that I look at it...that's not a bad project for me! LOL
Edited to give directions: I make 5 of the button holes in about 11 inches of fabric. Then I knit until the piece measures 24 inches and bind off. I block the pieces. Then I fold lengthwise with wrong sides together and with buttonhole band on top. I place my buttons correctly and then sew lengthwise. Button one side of pillow and insert pillow form. Button the other side of the pillow and TADA - finished pillow.
