What you’ll need:
4 FQs of fabric, preferably including two prints and two solids, like these beauties Westminster Lifestyle Fabrics provided.
Cutting mat
Quilting ruler
Quilting rotary cutter
A walking foot is recommended, but not necessary
After determining your fabric placement, set aside your border and cut your remaining three fabrics into 2.5” strips. I’ll refer to them as A (inner star), B (outer star), and C (background).
You’ll need about 2.5” x 12” for fabrics A and B and two strips about 2.5” x 16” each for fabric C.
Feel free to cut your strips a little longer if you like, this is just what it took for me to comfortably cut my
triangles.
Find the angled lines on your quilting ruler marked 30/60 degrees. Line one up on your strips (as seen above) to cut your triangles.
All in all you’ll need 6 triangles each of A and B and 16 triangles of C.
Next, lay them out in their correct spots. Maybe some of you would prefer to sew them into rows, but I chose to sew them into later triangle clusters in order to better maintain the triangle shapes as well as match up corners, as is seen above.
Taking one cluster, further break down the set so that one triangle is alone and three triangles are in a row on bottom.
Take two of your bottom triangles and place them right sides together. Sew them together using a ¼” seam allowance. Since 2 out of three edges on each triangle are cut on the bias and therefore are prone to a little stretch, if you don’t have a walking foot take care to allow them to carefully feed through, holding the triangles together, but not stretching them. You may use pins if you’d like, but I personally did not since the triangle sides do not have much length to work with. After each triangle is sewn, press your seams open (if you like to press to the side…just trust me on this one).
Once all three triangles are sewn into a row for the bottom, take the fourth triangle for the top point. There is no need to trim the dog ears yet, because as you sew the triangles together they are very helpful for matching up corners.
Continue to sew the remaining clusters together and arrange them in two halves. For each halve, sew the clusters together first and save the individual corner triangles for last. Finally, sew both halves together.
When sewing your clusters together, you may find it helpful to line up the seams by matching the center triangles together, as is shown above. Pin and sew accordingly.
Now that all of your triangles are sewn together, it’s time to trim. Don’t worry about the measurements; we’ll take care of that in a minute. The important thing right now is to line up your ruler so that there is an allowance for a ¼” seam all the way around the points of your star.
Once your block is nicely trimmed, it’s time to measure it so you can add your solid border. Mine measured at 6 ¾” x 7 ¾”. At this point I chose to make my border a teensy bit on the large size so I could nicely trim it down to be a perfect 8 ½” square finish (you may prefer to just use the exact dimensions needed, which would be 7/8” x 6 ¾” and 1 3/8” x 8 ½”; please do whatever you feel more comfortable with). So, for my short sides, on top and bottom, I cut two strips from my remaining solid fat quarter (fabric D) measuring 1 ¼” x 6 ¾” and sewed them into place. Next, I cut two strips measuring 1 ¾” x 9 ¼” and sewed them onto the long sides, completing my border.
Trim your block into an 8 ½” square, taking care to make sure your borders are even (if your measurements turn out like mine, the top and bottom borders were just a hair over 5/8” and the side borders were 1 1/8”).
And you’re done! One beautiful triangle star block for your Christmas in July quilt! Now sit back, enjoy a lemonade, and admire your handiwork.
