Just a few pins to hold the pillow seam steady while I sew 1/8" blindstitches. Once the blindstitches are complete you can't see the piping stitches peaking through.
Cutting the Front and Back
The pillow forms were 18" squares. To make a perfect cover--I cut front and back panels at 19" square. That's the secret--always cut fabric one inch larger than the size of the pillow form. Next, I serged all four sides of each panel. Set panels to the side.
I used 3/8" cotton cord. It is soft, and turns effortlessly around corners--making for easy sewing.
Piping is a plaid fabric and cut 2-1/2" strips with a rotary cutter. I made 3 pillow covers, and each pillow requires two yards of piping, plus a tiny bit more to ease the corners. I purchased 6.5 yards of cotton cord. The plaid fabric was 56" wide, so I cut 5 strips, and joined the strips with the serger. Then I like to serge the entire length of the large plaid strip.
Using a zipper foot on my regular sewing machine I slipped the cotton cord into the plaid fabric strip, keeping the zipper foot snug against the cotton cord and stitch. I lengthen the stitch to 2.8 or 3.0 so the fit is relaxed.
