If you do not wish to add the decorative pom pom trim, you can pin or clip the entire perimeter at this point.You can see how this will look in the image above (I pulled back one of the corners to show you the layout.yours will lay flat). Place the two smaller back pieces on top of that rectangle with their right sides down (touching the other right side of the larger (whole) rectangle that will be the front of the pillow.Place your larger (whole) rectangular piece of fabric facing right side up on your surface.Once both of your smaller pieces have them hem sewn into place, you'll lay out your pillow and start piecing it together to sew.You'll do this to both of the smaller pieces (as pictured above with my orange stitching). You'll do a simple basic stitch on top of it with a small backstitch and both the beginning and end. Head to your sewing machine with that turned and ironed edge to sew it in place.

Take your two smaller pieces (the ones for the back of the pillow that will overlap to form that opening), and turn one of the shorter sides of each piece over 1/2' and iron that in place, then turn it again another 1/2' and iron that in place.To do the 4' overlap, take the size of your front piece and add 8' to the width (so, in my case, 24+8=32), then divide that in half (32/2=16). The two smaller pieces are 12'x16' (I like an almost 4' overlap in the back, if you prefer a smaller overlap to make pillow insertion easier, take that into consideration and make it an inch or so shorter).For my 24'x12' pillow, I cut my larger piece right at 24'x12' (I'll be using 1/2' seam allowance so the finished pillow looks nice and full).
