How to quilt Diamond Hexagon cushion top using your walking foot

Welcome back to my very special Diamond Hexagon oversized cushion pattern. Yesterday, we pieced the cushion top. Today I’ll show you all my tricks for an easy quilting process. When looking at the design and choice of fabrics I made, I realized there was no need for fancy free-motion quilting. The design and the fabrics already have so much character, so I’ll do some subtle quilting to balance the ensemble.

Sandwiching your quilt

The first step you need to take is to sandwich your quilt with a backing and batting. For this project, I used Fabric Creations 100% Cotton Fabric for the backing, and Fairfield Toasty Cotton Natural Cotton Quilt Batting.

The project size is 32½” x 28½”, so I cut the batting and backing to 38″ x 32″ and then basted the layers together using Odif 505 Temporary Quilt Basting Adhesive Fabric Spray.

After waiting to ensure the basting spray was set, I went to my sewing machine and was ready to quilt using a walking foot and a Klassé Size 80/12 Quilting Needle. I had carefully planned the quilting – starting in the center and moving out – and I had three different thread colors that would help me make just the right quilting statement.

Section 1

I threaded my machine with Gütermann 30wt Cotton Thread in Golden Sunset to quilt the center of the quilt.

To set my diamonds, I opted to stitch in the ditch, starting at the center of the piece and moving my way outward, stopping at the solid color strip. Once I had the lines stitched, I buried the threads into the quilt using a Clover Self Threading Needle. If you’ve never tried a self-threading needle, you just don’t realize how your life could be made so much easier! You’ll notice there are two eyes on the needle. The one on top has a tiny V-shape right above it. Simply grab your thread, stretch it across the V-shape, and carefully slide it downward. It’ll move right through into the eye.

Use a Clover self threading needle to bury your thread ends.

Once that portion was done, I began quilting ¼” away from each seam, beginning with the smallest section in the middle and working my way out, stopping just before the solid color strip. Echoing the hexagon design felt just right for this project.

Section 2

I switched thread color and began quilting ¼” away from the seam on the solid color strip. I stitched in the ditch at the seams that extend to the corners of the quilt (the sections where two solid color strips connect). Then I quilted the other side of the solid strips extending to the corners of the quilt.

Quilt ¼” away from the seams.

Section 3

I switched thread color once more and stitched in the ditch between the diamond and half diamonds units surrounding the center piece. This time, I started at the edge of the solid strip and worked my way out. Then I quilted ¼” away from each seam, beginning beside the solid color strip and worked my way to the edge of the quilt.

The outer diamonds have been quilted with Gütermann Cotton 30wt thread in Autumn Leaves.

Remember to quilt in alternating directions, meaning if you quilt one line clockwise, quilt the next line counterclockwise. If you use the edge of your walking foot as a guide to echo quilting beside the seams, you’ll automatically do this.

Squaring off the quilt

Once all the quilting was done, I stay-stitched ¼” from the edge of the quilt and cut away the excess batting and backing. Normally I’d be ready to add a border to finish the quilt, but since I’m turning this project into a cushion, there was one more thing I had to do – square off the quilt. Or, in this case, ensure it was a perfect rectangle!

Squaring off the project using my Omnigrip ruler.

I pulled out my Omnigrip 20½″ x 20½″ Ruler and proceeded to square off one corner of the rectangle, then squared off the other corner on the same edge. Once these two were perfectly squared off, I folded my quilt in half, positioned the square ruler alongside my Omnigrip 8½″ x 24″ Ruler (to get the width I needed) and cut away the excess fabric and batting.

Fold the quilt in half to finish squaring off the project.

The final size of my Diamond Hexagon oversized throw cushion is 27½” x 32″.
