Quilt block

Friendship Star quilt block

A nine patch with four half-square triangles set pinwheel-fashion around a solid centre — a star with a slight spin to it, and one of the friendliest blocks for a first star.

Also known as Friendship Block.

Friendship Star earned its name from friendship and signature quilts, where each block was made and often signed by a different person before the whole was assembled as a gift. The plain centre square is the reason: it is a natural place for a signature in permanent ink.

Friendship Star cutting chart

Cut sizes include a ¼″ seam allowance: ½″ on squares and rectangles, ⅞″ on half-square triangles, and 1¼″ on quarter-square triangles. Pick a finished block size:

How it goes together

Four HSTs, four plain squares, one centre. The four triangles all rotate the same direction, which is what separates it from Shoo Fly — get one backwards and the star stops spinning.

Tips

  • Lay the block out on a mat before sewing and check that all four points swing the same way.
  • The plain centre is the traditional signature spot — sign before assembly, on fabric stabilised with freezer paper.
  • It is forgiving enough for a first star block and reads well at 6, 9 or 12 inches.

What it looks like in a quilt

A single block only tells you half the story. Set sixteen of them together and the secondary pattern appears where the blocks touch:

Friendship Star questions

Is Friendship Star the same as Sawtooth Star?

No. Friendship Star is a nine patch with four HSTs and reads as a spinning star; Sawtooth Star is a four-by-four grid with eight triangle points around a large centre square.

Change one thing and every number follows

Resize the block, swap a fabric, add sashing — the cutting list and the yardage recalculate as you go. No spreadsheet, no re-doing the math.
