- A copy of the templates
- 11 different scraps of fabric: 8 for the pinwheel, 1 for background, 1 for backing, and 1 for binding
- scrap of batting
Gather your supplies. I chose a rainbow of fabrics for the pinwheel. Download and print the templates. I like to iron a few layers of freezer paper to the back of my templates before cutting them out - they're more durable and (I think) the extra thickness makes cutting easier.

Cut the following pieces:
- 5" square of batting
- 5" square of backing fabric
- 2" x 24" strip of binding fabric
- 8 triangles for the pinwheel
- 4 background A pieces
- 4 background B pieces

Lay out your coaster. Alternate background A and B pieces around the outside of the pinwheel.

Line up the background pieces right-sides-together with the triangles. On the right is Background A lined up with a triangle, on the left is Background B lined up with a triangle and ready to sew. Notice the colorful "ears" peaking out behind the background.

Stitch the pieces together using a scant 1/4" seam allowance. Start stitching at the straight edge and stitch towards the "ears." Press the seams open. Lay out your coaster again.

Stitch together pairs of triangles. Press the seams open.

Stitch the squares together. Press the seams open. Make the quilt sandwich (top-batting-backing) and quilt your coaster. Trim. Bind. Repeat 3x more for a set of coasters. Cheers!
