Swirlybirds Mini-Quilt Pattern

Give it a Whirl Blog Hop! The only rule is that you have to use somwthing that whirls. See the list of participating designers at the bottom of the page.

Start with a Three-Dimensional Pinwheel Quilt Block

Gather some scraps so you can practice the technique before using it in a quilt. You will need:

  • (4) 3-1/2″ squares of the fabric you are using for a background. Mine is a red and white swirl.
  • (4) 4″ squares of the fabric you are using for your dark. Mine is a red.
  • (4) 4″ squares of the fabric you are using for your light. Mine is a white.

The Traditional Method of Making HSTs

The Traditional Method of making Half Square Triangle Blocks (HSTs) is to place a 3-7/8″× 3-7/8″ dark square right sides together with a 3-7/8″× 3-7/8″ light square.  Draw a diagonal line on the back of one square.  Sew 1/4″ on both sides of the line.  Cut on the line and press to the dark.  You will have made two blocks that measure exactly 3-1/2″× 3-1/2″ square. 

The HSTs for a Three-Dimensional Pinwheel Quilt Block

My personal preference is to cut the original squares slightly too large (4″) and square up the HST to 3-1/2″ later on.  You can tell that I am a big fan of the Quilt-in-a-Day square-up rulers. You have just the lines you need and no more.

Squaring Up an HST for a Three-Dimensional Pinwheel Quilt Block

Using the HSTs to make a pinwheel

Fold your HSTs in half along the seam (below right.) One half of the triangle will be dark and the other will be light. Placing the seam on the left, fold the upper right-hand corner down against itself. (below left.)

The HSTs for a Three-Dimensional Pinwheel Quilt Block

You have two choices here: fold the light over the dark, or the dark over the light. I laid them against the fabric I am using for the background and decided I liked the dark over the light better.

Which one do you like better?

Stay stitch the pinwheels 1/8″ from the edge. Did you notice that they are actually all the same block? You turn them in different directions to make the design.

Quilt Blocks for a Three-Dimensional Pinwheel Quilt Block

Sew these blocks in groups of two. Just like before, the top and bottom rows will be identical.

Sew them together and you have a 6-1/2″ pinwheel!

The Swirlybirds Mini-Quilt Pattern

The pattern calls for an 11-1/2″ center square, but that is because it was the size of the block I had fussy cut. You can add these pinwheel accents to any size center square – like all the ones you have been making all year!
