Block of the Week 35 Mosaic #2

Block of the Week 35 Mosaic #2

In Week 22, we made a Mosaic block. This week, we are making a second Mosaic block. Most of the time, Mosaic quilt blocks are made up of Half Square Triangles. I decided we would throw in some Flying Geese with some Half Square Triangles. As we have done before, we will making everything slightly larger and trim them down to the exact size.

I will be giving you some optional layouts for this block as well.

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 3 - 4" squares

Fabric B - Cut 3 - 4" squares

Fabric C - Cut 2 - 4" squares

Fabric D - Cut 4 - 4" squares

Fabric E - Cut 1 - 7 1/2" square


Half Square Triangles: Draw a diagonal line on the wrong side of the 3 Fabric B squares and 1 of the Fabric C squares.

Pair 2 Fabric A and B squares, 1 Fabric B and C square, and 1 Fabric A and C square.

With right sides together, sew 1/4" on both sides of drawn line.

Cut on drawn line.

Repeat this for all the Half Square Triangles. Press toward Fabric A for the A/B and A/C Half Square Triangles and Fabric C for B/C Half Square Triangles. You will have 8 slightly oversized Half Square Triangles.

Trim these Half Square Triangles to 3 1/2".

Layout the Fabric A/C and B/C Half square Triangles as shown.

Sew the Top 2 and Bottom 2 squares together. Press seams open.

Sew these 2 rows together. Press seam open. This center square should measure 6 1/2" square.

Flying Geese: Using a marking tool like the Magic Wand, mark the sew lines on the wrong side of the 4 Fabric D squares.

Take 2 of the above squares and lay them right sides together on the Fabric E 7 1/2" square. (Leave just a little bit of the Fabric E showing on the edges as shown)

Sew on both drawn lines.

Cut apart in between the sew lines.

Press toward Fabric D.

Lay another Fabric D square right sides together on the units from above as shown.

Sew on the drawn lines and cut apart in between the sew lines. Press toward Fabric D. You will have 4 slightly oversized Flying Geese.

Trim the Flying Geese to 3 1/2" x 6 1/2". 

We have all the units we need to complete our Mosaic block. This is how I arranged the pieces. (Scroll down to see a few other options before you sew your pieces together).

If you flip the Flying Geese around, the design changes more to a star.

And you could flip the corner Half Square Triangles and you will get this...

Whichever layout you choose, you will sew the top, middle, and bottom rows together. Press toward the Flying Geese.

Sew the 3 rows together to complete the block. Press seams away from the center.

Mosaic #2 and Week 35 is complete.
