It is hard to believe, but we have made it into our 5th month and Week 18! We are making the Whirlwind block with Quarter Square Triangles. We will be cutting our squares diagonally which means we will be sewing on some bias edges. Be sure not to pull on your fabric pieces as you guide them through your machine so that you don't have any distortion.
As we have done in previous blocks, I have made sure that these units will be slightly oversized and you will trim them down to the exact size before sewing them together.
You will need 2 colors and a background
Fabric A - Color 1
Fabric B - Color 2
Fabric C - Background
Fabric A - Cut 2 - 7" squares
Fabric B - Cut 1 - 7 1/2" square
Fabric C - Cut 1 - 7 1/2" square
Cut the 2 Fabric A squares in half on the diagonal as shown. You will have 4 triangles.
Cut the Fabric B and C squares twice on the diagonal as shown.
Quarter Square Triangles: Layout the Fabric B and C triangles as shown and sew them together.
Press toward the Fabric B triangle. You will have 4 Quarter Square Triangle units that look like this.
You are going to sew the Fabric A triangles to the above units as shown in the first picture. To do this, fold the Fabric A triangle in half as shown in the second picture to find the middle of the long edge and make a small crease.
With right sides together, line up that middle crease of Fabric A with the seam in the Fabric B/C triangle unit, use a pin to hold it in place.
Sew these together and then press toward the Fabric A triangles.
Repeat this step so that you have 4 units. They will be slightly oversized so that you can trim them down to 6 1/2". (I used my 6 1/2" Bloc Loc Ruler to trim these down.)
**Look at the second picture below to see how you need to line up whichever ruler or tool you use to make sure this unit stays square.
Use the seam on the Fabric B/C triangles and the 45 degree angle of the ruler before you trim.
Once you have trimmed the 4 units to 6 1/2", lay them out as shown.
Sew these together like a 4 patch. First Sew together the top 2 units and then the bottom 2 units. I pressed these seams open.
Sew the top and bottom pieces together to complete the block. I pressed this final seam open as well.
And there you have it, your Whirlwind block is complete. Week 18 is done!
