Ready for some more Half Square Triangles? Or block for Week 22 is called Mosaic. It is made using 16 Half Square Triangles. I used the Teal, Aqua and Yellow fabrics from our May bundle and added in a purple from a previous month.
As we have done several times, your Half Square Triangles will be just slightly larger than they need to be so that you can trim them down to their exact size for more accurate piecing.
All fabrics are cut the same size this month, so cutting shouldn't take you any time at all :)
You will need 4 colors and a background
Fabric A - Color 1
Fabric B - Color 2
Fabric C - Color 3
Fabric D - Color 4
Fabric E - Background
Fabric A - Cut 4 - 4" squares
Fabric B - Cut 2 - 4" squares
Fabric C - Cut 2 - 4" squares
Fabric D - Cut 2 - 4" squares
Fabric E - Cut 6 - 4" squares
Draw a diagonal line on the wrong side of the 2 Fabric C squares and the 6 Fabric E squares.
Pair the fabrics as shown below. Fabric A with 2 Fabric E and 2 Fabric C squares, Fabric B with 2 Fabric E squares and Fabric D with 2 Fabric E squares.
Sew 1/4" seam on both sides of the drawn line.
Cut apart on the line.
Press toward the darker fabric.
Repeat this for all of the Half Square Triangles, always pressing toward the darker fabric.
Trim all of the Half Square Triangles down to 3 1/2" square.
You will have 16 - 3 1/2" Half Square Triangles.
Layout the Half Square Triangles as shown below.
You can chain piece these through your machine as you will need 4 units that look like this.
Sew the top pieces together and press toward the darker Fabric (Fabric A). Sew the bottom pieces together and press toward the darker Fabric. (Fabric B).
Sew these together, interlocking the seam in the middle.
To press, I used the tip of picking out the few stitches in the seam and then manipulating the seams to go in opposite directions for less fabric bulk.
You should have 4 units that measure 6 1/2".
Take the 4 units from above and lay them out as shown.
Sew the top 2 units and the bottom 2 units together and press open.
Sew these rows together to complete the block. Press final seam open.
Your Mosaic block is complete!
