Out of the half yard of felt, cut:
(1) 17" x 17" piece for cover front
(1) 17" x 10 1/2" piece for the back
(1) 17" x 9" piece also for the back
Out of your felt scraps, cut out bunting shaped triangles-mix and match the colors until you have enough. You can either freehand the triangles like I did or make yourself a template out of cardstock so each triangle is the same size. Of course, you don't necessarily have to use triangles. Here are some of the most common bunting shapes.
Once you have your pieces, lay them out on the pillow cover front. You can arrange them any way you like. Make sure your bunting pieces are far enough away from the edge so as to not get caught in the seam allowance. When you're satisfied, pin each one in place.
Then take your pillow cover front piece to your machine and sew the bunting in place with a 1/4" seam allowance. The front is done. Set that aside for now.
Now grab one of the pieces that you cut for the back side of your pillow cover and fold the long side over 1/2" and pin. Keep folding and pinning all the way down the long side. Do the same with the other back piece.
Once they're both pinned, you're going to sew all the way down the long side, very close the edge, taking the pins out as you go. Do this for both pieces.
Set your back pieces aside and let's take a look at your front piece again. On mine, I had 3 bunting pieces that were in danger of being sewn into the seam...we don't want that! Fold them in and pin them out of the way like shown.
Now we're going to sew the pillow cover together. Place the front cover right side up. Then place one of the back pieces right side down on top of the cover front. (Doesn't matter which one!) Match up the 2 long sides.
Take the other back piece and place it on the other side, right side down. These pieces will overlap. Pin all around.
Next, sew all the way around the outside of the cover, using a scant 1/4" seam allowance and back stitching at the beginning and end. Remove pins as you sew.
Once you're done, clip the corners but be careful not to cut through the thread!
Turn the cover back out so that it's the right way and remove the pins used to hold the bunting out of the way.
Slide the pillow form into the cover through the opening in the back. It may take a little bit of wiggling to get it centered as there will be a bit of extra room around the sides of the pillow. ALL DONE!
