Rainbow Valley Quilt

finished rainbow quilt

Create a quick-and-easy strip-pieced Rainbow Quilt and accent it with beautiful 50 wt. Cotton Thread in assorted rainbow shades. This quilt utilizes half of a rainbow-shade jelly roll, with additional strips of black fabric. Change it up by using any jelly roll collection, with a neutral solid to break up the other colors.


Finished quilt measures approximately 42” x 54”.

The good news is that no cutting is needed when working with jelly rolls! However, if using solid fabric yardage, you’ll need to cut the same amount of strips from the solid as the prints in the jelly roll.

This Rainbow Valley quilt features 12 rainbow shades and 12 neutral shades (shown in black) to create a 42″ x 54″ quilt. Easily make a larger quilt by adding a few more strips.

To change it up, choose a fun rainbow-themed print fabric to alternate with the rainbow solids.

Decide on the color arrangement for your chosen fabrics. Go with a rainbow pattern, separated by black, as shown, or choose your own adventure.

Thread the needle and bobbin with a neutral color of Sulky 50 wt. Cotton Thread. This lightweight, strong thread is perfect for piecing, as it creates a virtually invisible seam from the right side.

Stitch the strips together using a 1/4″ seam allowance. If your machine has a laser light, utilize it to ensure a perfect seam allowance width every time.

When piecing is complete, place the backing fabric wrong side up on a flat work surface. Spray it evenly with KK 2000.

Center the batting rectangle over the backing, smoothing with your hands.

Spray the quilt top wrong side with more KK 2000. Center it right side up over the batting, and then smooth with your hands without stretching the fabric.

Add a few Clover Wonder Pins to further secure the quilt layers.


Quilt the Rainbow Quilt as desired. Swap thread colors for different rainbow fabric shades to really accent the color gradations.

The Rainbows & Unicorns 50 wt. Cotton Thread Palette for Quilting gives you a bunch of colors to choose from at a great bundle price.

The featured Rainbow Valley quilt was long-arm quilted with a computerized design. At each quilting row, a different thread color was used in a rainbow pattern. The back of the quilt looks just as pretty (dare I say even prettier!) than the front.

Once quilting is complete, trim the edges so they’re even.

Bind the quilt using your preferred method. For a nice, clean back, hand sew the binding fold to the quilt back only, using a slipstitch. Clover Wonder Clips are your best friend during the binding process!
