Hello! For this week’s quilt block pattern, I’m teaching you how to make a 12-inch Friendship Star quilt block. If you’re new here, I share a free quilt block pattern for a quilt block each week.

Some of the block patterns are older posts from our site that didn’t include printable instructions; this is one of those posts. I’ve added directions, illustrations, and a print function for you.

What is a Friendship Star Block?

A Friendship Star quilt block is a traditional and popular quilt block design that features a simple yet visually striking star pattern. It is often used in quilts to symbolize friendship and unity. Hereโ€™s a breakdown of the components and construction of a typical Friendship Star quilt block:

Components

  1. Squares: The block is composed of squares.
  2. Half-Square Triangles (HSTs): These create the star points.

Construction

  1. Center Square: The center of the block is a single square, usually of a solid color or a patterned fabric that contrasts with the background.
  2. Corner Squares: Four corner squares are typically in the same background fabric.
  3. Half-Square Triangles: Four (half-square triangle) HST units are placed around the center square to form the star points. These HSTs are made by sewing together two triangles, one of the background fabric and one of the star fabric.

I’m working on a scrappy, colorful quilt with blocks in mostly monochromatic color scheme prints on a dark gray background.
