Round Three

This round uses quick pieced strip sets to make a wide sail windmill block border.

Materials for this round

You will need
  • Fourteen 12in x 1 3/4in strips of assorted fabric
  • Fourteen 12in x 1 3/4in strips of background fabric
  • Two 24 1/2in x 1 1/2in strips of background fabric for side sashing
  • Two 26 1/2in x 1 1/2in strips of background fabric for top and bottom sashing
If you are using the fabric provided with the last block, then you can choose any of the fabrics for your strip sets.
There are twenty eight blocks in the border, and each strip set makes two blocks.
I chose to use three strips in each of four fabrics, and two strips of the fifth fabric. As long as you work in even numbers, you can choose a different combination if you wish. Please take care to cut these economically and sensibly to ensure enough fabric will be left for Four. In particular, please leave at least a 7in length of any full width lengths of backing fabric for the biggest sashing strips.
Otherwise choose new fabrics and a background fabric for this round.

Method for No Waste Wide Windmills

The method given is very quick and easy, but the windmills are not quite as elegant to tile as a traditional windmill block. You have enough fabric to make fourteen positive and fourteen negative traditional windmill blocks if you prefer. You will need a total of twenty eight 3 1/2in unfinished size blocks, but you will have to find your own instructions! The instructions given below are the no waste easy method for wide windmill pairs.
This method uses a strip set to make all the units for a postive and negative windmill pair. This is why you need fourteen strips of background and coloured fabric.

Cutting Instructions

Cut fourteen strips of background fabric, 12in x 1 3/4in, and fourteen 12in x 1 3/4in strips of other fabrics. I cut three strips of the unused fat quarter, three in three previously used fat quarters, and two strips of the most used fat quarter.

Sewing the wide windmills

The first strip set
The first strip set
  1. Take a background strip and a coloured strip and join as shown.
  2. Cross cut the strip into four 3in wide units.
    Four 3in units Two sets of four triangle units
    Left: Four 3in units
    Right: Two sets of four triangle units
  3. Make sure all the units are the same way up! This is important, as your windmill sails will not work otherwise!
  4. Using the 45 degree line on your ruler, crosscut each square diagonally from corner to corner. Keep checking that the square is the correct way up every time! You will end up with two sets of four matching triangles.
  5. Put one set of triangles to one side for a minute. Take the other set and place the triangles RS togther in right angled pairs ready for piecing.
    Placing the triangle pairs together Triangle pair ready for sewing
    Left: Placing the triangle pairs together
    Right: Triangle pair ready for sewing
  6. Organise the second set of triangles in the same way and chain piece each pair. You will have a string of four triangle pairs.
  7. Press the pairs open, and join each half windmill unit to form two windmill blocks.
    Half windmills
    Half windmills
    Full windmills
  8. Square up your blocks to 3 1/2in if needed.
  9. Repeat the process with the remaining thirteen background coloured fabric strips. You will end up with twenty eight windmill blocks.

Making up the second Border

  1. Arrange your blocks as you prefer around the completed sashed Round Two unit.
  2. Assemble the six left hand side blocks into a short border, and attach to the lhs of the Round Two unit.
  3. Repeat with the six rhs blocks, and attach to the Round Two unit.
  4. Assemble the eight blocks in the top and bottom borders and attach to the Round Two unit.
  5. Your square should now measure 24 1/2in


  1. If your square is not 24 1/2in, you will need to adjust the sashing, The unfinished square after sashing should be 26 1/2in.
  2. If your square is ok, cut two strips of background fabric 24 1/2in x 1 1/2in and attach to the sides of the Wide Windmill border.
  3. Cut two 26 1/2in x 1 1/2in of background fabric for the top and bottom sashings, and attach to the quilt top.
  4. You have now finished Round Three!
If your Round Two unit came with extra fabric, please send the remaining fabric with your Round Three unit to the next quilter. If not the Round Four quilter will add the fabric of their choosing. Take a photo of your block for the album, and then parcel up the block and extra fabric if required. Then send your parcel to the next person in your Round Robin group, and wait for the next set of instructions.
