Pattern Tutorial

A friendship star quilt block is easy to make. It's very beginner friendly as it's made with half square triangles. Make 12 inch, 9 inch or 6 inch stars!

An interesting piece of history... In the USA when the West was being settled in the last half of the 1800s, friendship quilts were sometimes given by their friends to the women headed West.

Oftentimes, the center square was embroidered with the names of friends being left behind. Can you imagine having such a gift!

Friendship Star Block Measurements

For great effect use at least two fabrics in contrasting colors. In this tutorial I have designated fabrics as follows

  • Fabric A = the star (print fabric)
  • Fabric B = background (white fabric)

Here are the unit cutting measurements for a friendship star block in three common sizes...

  • Fabric B: Cut 2 (3 1/4) inch squares
  • Make 4 Half Square Triangles and Trim To 2 1/2 Inch
  • Fabric B: Cut 5 (2 1/2) inch squares

9 Inch Finished Block

  • Fabric A: Cut 2 (4 1/4) inch squares
  • Fabric B: Cut 2 (4 1/4) inch squares

  • Fabric B: Cut 5 (3 1/2) inch squares

12 Inch Finished Block

Friendship Star Quilt Block Instructions

Step 1 Choose your block size from above and cut squares as indicated. Make 4 half square triangles using one print (Fabric A) and one background (Fabric B) fabric square for each. (Oops, yes, I forgot to photograph by themselves the HSTs I used to make this friendship star quilt block. So, of course I had to make more. :-))

Press the seams toward darker fabric. Trim to size.

Row 1: With right sides together, place the half square triangle (HST) from column 2 on top of the plain square from column 1. Sew the units together using a 1/4 inch seam along the right side of the units.
