Please note: Even if you share photos on other social media sites or your own blog, to be eligible to win one of the give-aways, you still need to upload the photo on this site.
Spilt Quarter-Square Triangles (SQST)
For this week’s Aiming for Accuracy lesson, I’ll refer you to the Spilt Quarter-Square Triangle tutorial that I’ve created.
While you could cut your fabrics on the bias to create the segments used to complete this week’s pinwheel blocks, I strongly believe that it’s easier far more accurate to start with oversized squares and trim the segments to the desired size for assembly into the quilt block.
Lesson 3 – Unit B5
This unit is made up of 16 SQST segments that form four mirrored pinwheel blocks separated by sashing.
When I originally designed this unit, my intention was that the fabric represented by P1 and P3 (i.e. the half-square triangles) would be the same, resulting in a very dramatic overall unit. However, that would have required eight (8) 6″ squares and I wasn’t able to cut that many from one fat quarter. That said, if you are using yardage instead of fat quarters, you can use the same fabric if you like.
When choosing fabrics for this block, make sure that there’s good contrast between all fabrics used so that the pinwheels stand out. Due to the mirrored nature of creating the SQST segments, you won’t be able to have four different pinwheels in Unit B5 (unless you want to have four extra blocks that aren’t required).
Cut your fabrics using the following cutting instructions.
Following the SQST tutorial, create the 16 SQST units. Trim these units to exactly 5.5″ squares.
Layout the 16 units following the diagram above to form the four pinwheel blocks.
Stitch your four pinwheel units together. If you are pressing your seams to one side, be sure to treat these units as a four-patch and spiral the seams to reduce bulk, as explained in Lesson 1. These pinwheel blocks should measure 10.5″ squared.
Attach the two 10.5″ x 1.5″ sashing strips in between the pinwheel blocks on each side.
Attach the long 21.5″ x 1.5″ sashing strip in between the two pinwheel block columns from above, making sure to line up the pinwheel units and middle sashing strips as you go. To achieve this, sew the sashing to one side, press. Mark lines in the seam allowance on the other side of the sashing strip that you’ll use to match up the seams of the pinweel block column being attached.
Completed Unit B5 = 21.5″ W x 21.5″ H
