First, determine how large you want your pillow. I chose my size based on the embroidery design. I made my pillow 7" x 10". My cut dimensions are 8" x 11". Find your center and mark it for placement of your design. I simply fold my fabric in half vertically then horizontally to find the center. I've also cut the fabric large enough, then embroidered my design, then cut to size.
This is a close up of the torn edge. Nice and straight, but I should have pressed before snapping the pic.
Now take the long piece and remove the floss from the piping but DO NOT cut it. Now use your seam ripper to remove the stitching from your piping. You want to expose the cording inside, because you are going to cut it.
I'm a little ahead in this next shot, but my camera just wasn't cooperating. I tried to zoom and darken the photo. You can just see the hem at the bottom. Now pin the two ends together but do not pin it to the pillow yet. Take your tail of your floss and restitch it to the piping. When you get to the end and on your last stitch. In this photo, it's the one right at the seam, bring your thread up at the last mark or right at the bottom of the next stitch and bring it to the bottom as shown.
Now you want to attach your ribbon to the top if you want it to hang from a door. You could omit this step if you just want a pillow. I used a 20" long piece of ribbon. Measure the top piece to find the center. Place your ribbon 5 inches apart from outside edge to outside edge as shown. Make sure the ribbon is straight and will hang the way you want. Pin it to test it if needed. Baste the ribbon in place.
Now place your backing piece to the top piece right sides together making sure your ribbon is out of the way. You may want to pin this to the middle of your pillow to keep it out of the way. Start at the bottom and stitch all the way around the pillow on the same piping stitch line leaving a 3 inch opening at the bottom for turning. Clip your corners to remove the bulk being careful not to clip the stitches. Turn right side out, and use something pointy like your scissors to push out the corners. Stuff your pillow to the desired thickness using polyfil and pin the bottom closed.
UPDATE: I AM SO SORRY THAT SOME OF MY PICTURES ARE MISSING. I MISTAKENLY DELETED THEM FROM PICASA AND THAT RESULTED IN THEM BEING DELETED ON MY BLOG. I AM GOING IN NOW TO TRY TO RECOVER MOST, BUT SOME OF THEM ARE JUST GONE. PLEASE FEEL FREE TO EMAIL ME WITH QUESTIONS THOUGH. I'LL TRY TO GET ANOTHER PROJECT DONE SOON TO REPLACE THESE.
