History of the Friendship Star Quilt Block

Tradition of the Friendship Star quilt block is friends would each make a block in their fabrics and sign the block. In the 1800’s, when people were heading west, friends would exchange blocks before moving on to the next settlement. The blocks could then be sewn together to make a quilt that reflects all of their friends as they took their journey across the country – keeping warm thoughts of the times together.

The basic version of the friendship star quilt block has squares in the corners. Or you can use half-square triangles in the corners as a variation. Other variations include using a third color, which is referred to as Simplex Star.

Instructions

Step 1: Cut your fabric

For each quilt block, you will need a total of five (5) squares and four (4) half square triangles.
Start by cutting four (4) 3-1/2-inch squares from your background fabric and one (1) 3-1/2-inch square from your star fabric, referring to the chart above. These will be the center and corner squares of your block. Set aside. I'm making a finished 9-inch block size.
Cut two (2) 3-7/8-inch squares from both your star and background fabrics.

Step 2: Make half-square triangles (HSTs)

For each quilt block, make four (4) half square triangles the same size as your squares from both fabrics. See 7 Ways to Make Half Square Triangles.
Make sure to trim your half-square triangles.

Step 3: Layout your block

Lay your pieces out in this format, three (3) rows of three (3). The half square triangles (also referred to as hst units) are on each side of the center square.

Step 4: Sew rows together

Sew the blocks for each row together, right sides together with 1/4-inch seam allowance and press seams.
Match the seams and sew all three (3) rows together. And now you have a friendship star quilt block!
