Block of the Week Block 14 Ohio Star

Doing something new this week, Quarter Square Triangles (Hour glass units). There are several methods to doing Quarter Square Triangles, we are going to do one of them. 

You will be making slightly oversized units and trim down before you continue for the best accuracy.

You will need 3 colors and a background

Fabric A - Color 1

Fabric B - Color 2

Fabric C - Color 3

Fabric D - Background

Cutting:

Fabric A: Cut 1 - 4 1/2" square

Fabric B - Cut 1 - 6" square

Fabric C - Cut 2 - 6" squares

Fabric D - Cut 4 - 4 1/2" squares

And Fabric D - Cut 1 - 6" square

Sewing:

Draw 2 diagonal lines on the wrong sides of Fabric B, C, and D 6" squares as shown.

First you are going to make Half square Triangles with the following pairs of squares.

Sew 1/4" seam on both sides of one of the drawn diagonal lines.

Cut apart on the drawn line.

Press toward Fabric C. You will have 4 Half Square Triangles as shown.

To make the Quarter Square Triangles, you will do the same process you use for Half Square Triangles by sewing 1/4" seam from both sides of the drawn diagonal line. Using one of each of the sets from above, place the HSTs right sides together, making sure the fabric C triangles are opposite of each other as shown.

Repeat for both sets. Cut apart on drawn line.

Press these seams open. You will have 4 oversized Quarter Square Triangles.

Trim these down to 4 1/2" units. Using the 45 degree line on your ruler, line this up on your seam to make sure you are cutting the unit straight.

Layout the pieces of your block as shown.

Sew these units together into rows, pressing toward the Fabric A and Fabric D solid squares.

Sew the rows together to complete the block. Press these seams open.

You have completed the Ohio Star block. I hope you enjoyed making these Quarter Square Triangles.

Don't forget to post your pictures on the Ruth's Stitchery Facebook page to be entered into our April drawing.
