Hunter's Star Quilt Block Pillow

I have always loved the Hunter's Star Quilt Block. Lately, I've been using a lot of HST's for my projects. With this project, I used the Crazy 8 method. (You will need 16 HST's total) I used a dark purple, and contrasting white. The back is solid purple. The tutorial for this pillow showed an envelope back, but I decided to install an invisible zipper instead. The finished pillow is a 16" x 16".
