Step 1: cut a piece of fabric the size of your desired pillow. Mine is 24" by 24". I appliquéd two ink jet printed pieces on to make the pillow top more interesting.
Step 2: Cut 2 pieces of muslin 24" by 18". Hem one right and one left side of each piece along the 24"edge.
Step 3: Lay these pieces right side together onto the pillow top piece and stitch along all 4 sides.
Step 4: Turn the pillow cover right side out and press. Sometimes I like to top stitch 1/4" along the edge of the piece. It gives the look of a piping and adds a nice touch.
Step 5: Pass the Stuffing Please. You can buy pillow inserts at your local fabric store, but I prefer to make mine. It's quick and easy and inexpensive. You can also get a very nice, plump looking pillow, any size you prefer. Start by sewing a simple pillow sack the same size as your finished pillow top, or even a bit larger. Leave an opening about 6 to 8", large enough to add the stuffing. Add lots of stuffing and spread it evenly into the corners and throughout the sack. Sew up the opening and insert into your pillow top.
Step 6: Sit back and enjoy. Cost to make: 2 hours of your time and $10. Looks like a million.
