How to Construct the Mosaic Pinwheel Block – 12″ Finished Block

  • Draw a diagonal line on the wrong side of each of the white fabric squares. We used a Frixion pen as the mark can be easily ironed off.)

  • Place the white fabric squares on top of each the coloured fabric squares with right sides facing. (ie. The wrong side of each of the fabrics should be facing outwards.)

  • You should now have 16 half square triangles – 8 for each colour.

  • Now it’s time to trim up each of the half-square triangles. We want to trim them back to 3 1/2″. Check out our tutorial here on how to do that – How to Square Up a Half Square Triangle.
  • Once your half square triangles are trimmed, you ware now ready to piece it together. Lay out the triangles as shown below.
