What You'll Need

Equipment / Tools

  • Fabric scissors
  • Fabric tape measure
  • Rotary cutter
  • Cutting mat
  • Sewing machine
  • Sewing needle


  • 100% cotton velvet
  • Pins
  • Stuffing
  • Sewing thread


  1. Cut Fabric for Triangular Pillow

    Cut fabric 21x31 inches using fabric scissors or a rotary fabric blade. Be sure to do this step on a self-healing cutting mat. This will protect your surface and help you cut perfectly straight lines. All seam allowances for this project are 1/2 inch. Fold the fabric rectangle in half with the right sides together and pin. (The velvet side of the fabric should be facing inside.)

  2. Sew Sides of Triangular Pillow

    Stitch a side seam across from the fold, leaving an opening in the middle of the seam for turning. Be sure to use a thread the same color as the fabric. Pin and stitch one of other shorter sides closed as well.

  3. Make Center Marks

    Mark the folded edge perpendicular to the last open side. Use a fabric pen to prevent bleeding ink. This line will be on the inside of the pillow when you're finished. Open the pillow holding the marked line, and bring it toward the first seam you stitched. Pull tight to see the wedge shape. Pin and stitch the opening closed.

  4. Press Seams and Finish

    Turn the pillow right side out and press seams with an iron. Pressing the seams will help the triangular pillow maintain its shape while stuffing. Find the opening along the side of the pillow. Insert batting, making sure you stuff it all the way into the corners until the wedge pillow is full. To finish, whipstitch the opening closed.
