"Double Pinwheel Whirls" 
paper foundation piecing 1/4 unit
for making this Block

This block could range in size from 6 inches to 12 inches. I show it here to make an 8 inch block. Use graph paper to draw the first 1/4 block. Then copy all further blocks from your original. Do not make copies of copies as the size will change. You will need to make 4 units for each block. Leave at least a 1/4 inch seam allowance around each separate unit.  If you are new to paper piecing - see these two articles for lots of how-to and links information.  

Above is a grid showing the 1/4 block you can draw easily to make your paper foundation pattern on graph paper. This unit would be 4" x 4" to make an 8" block or 3" x 3" to make a 6" block, etc. You need to add a 1/4" seam allowance around the outside edge of each 1/4 unit before assembling your block.

Below is an enlarged view of the 1/4 block numbered for sewing. The blue dashed line shows the quarter inch seam allowance that needs to be left around each unit.

Note: If your section #1 in the 1/4 unit below is slightly different from the exact way I drew it - it's OK! As long as the 1/4 Unit that you draw is used to make all the blocks you will have your block forming a nice pinwheel shape.  Or, make two different angled #1 1/4 sections and assemble them into a 2nd version of the block to mix with the first.
