Sewing Tutorial: Make A Rainbow Book Cover

Homework has never looked better.

Doesn’t this rainbow composition book cover just make you smile? And smiles during homework time are a very good thing! Our Omnigrid® OmniArc™ ruler was used to create the colorful arcs of the rainbow on this easy-sew project. How? The OmniArc™ ruler is unique in that it has curved grooves to guide your rotary cutter as you cut – it’s easy to create perfect arcs and circles. Now that’s wonderful.

Omnigrid supplies: Rotary Cutter & OmniArc Ruler

The OmniArc™ ruler is essential to this project, as it’s what you’ll use to cut the arcs of the rainbow. The 28mm rotary cutter is  important, too!

Practice using the OmniArc™ ruler by cutting some scrap fabric first. It will give you a feel for the ruler and confidence when you are ready to cut your rainbow arcs.

Tip: Be sure to line up the vertical and horizontal sides of the fabric with the radius lines on the OmniArc™ ruler before you begin cutting the arcs.

After you’ve practiced a bit, gather the rectangular rainbow fabric pieces you prepped.

Cut:

1) Cut 5 pieces paper-backed fusible adhesive lite the same sizes as your rainbow fabrics. Fuse the paper-backed fusible adhesive to the wrong side of your rainbow fabrics according to manufacturer directions.

2) Fold the pink fabric in half, wrong sides together, so it now measures 7” x 7”.

3) Align the ruler with the left side and corner of the fabric along the radius lines on the ruler.

4) Hold the ruler tightly and cut an arc along groove #6. Start at the bottom of the groove and work up toward the top. Keep the ruler in place and make another cut along the #5 groove. You should now have a perfect rainbow arc. Put the rest of the pink fabric aside, saving it for another project down the road. 

The yellow fabric shown is illustrating the 3 pieces of fabric you should have each time you cut an arc: a top corner (save for another project), the middle arc (use for your rainbow), the center piece (save for another project). Make sense?

5) You are going to repeat the arc-cutting process with the remaining 4 rainbow fabric colors. Fold each fabric in half, line up on the radius and make two cuts as noted below. (Each arc will be smaller than the one before it; the purple fabric will be a half circle.)

  • Orange fabric: cut along #5 and #4
  • Yellow fabric: cut along #4 and #3
  • Aqua fabric: cut along #3 and #2
  • Purple fabric: make only 1 cut along #2

Apply:

6) Fold the outer cover in half and crease gently to find the center. Open and lay flat.

7) Remove the back paper from the rainbow arcs.

8) Center the pink arc on the outer fabric cover, lining up the bottom edges of the arc with the bottom edge of the outer cover.

9) Fuse the pink arc in place.

10) Build the rainbow by following steps 7-9 for the remaining arcs.

11) Fuse the outer cover onto the Thermolam® according to manufacturer directions.

12) Topstitch along both sides of each arc with a ⅛” seam allowance.

Embellish:

13) Fuse a piece of 5” x 5” paper-backed fusible adhesive onto the wrong side of the white fabric. Draw a cloud shape and cut it out.

14) Position the cloud above the rainbow to the right. Be sure to leave a 1” margin between the cloud and the edges of the outer cover. Fuse onto fabric and topstitch along all sides of the cloud with a ⅛” seam allowance.

15) Using a water soluble fabric marking pen, draw eyes and a mouth on the cloud. Hand embroidery the details on the cloud.

16) Using the fabric pen, draw 9 raindrops falling from the cloud. 

17) Using embroidery floss in colors of your rainbow, stitch the raindrops.

Assembly:

18) Fold each 11” x 10” inner flap piece in half so the flaps now measure 5” x 11”. Place a length of ribbon ¼” in from the folded edge and topstitch along both sides to secure.

19) Repeat for other flap.

20) Place flaps on lining panel, lining up raw edges. Baste in place. 

21) Place the outer fabric cover, right sides together, over the lining fabric. Pin.

22) Stitch around all sides with a ¼” seam allowance leaving a 5” gap for turning along the right side. Backstitch at the beginning and end.

23) Clip corners and gently turn right side out, poking out the corners with a point turner. Push opening seam allowances to the inside. Press both sides.

24) Topstitch along the perimeter with a ⅛” seam allowance making sure you stitch the opening on the side closed.
