BOW #30 Pinwheel 2

Another Pinwheel block uses units that are a combination of QST and half square triangles:  a QST becomes one of the half-square triangles.

For a 12" finished Pinwheel you will need:

(4) Light/Dark1 Quarter Square Triangle units--or half units (a triangle), made from 7-1/2" squares
     (See BOW# 28   for instructions for making Quarter Square Triangles)
(4) Half-square triangles, made by cutting (2) 6-7/8" squares in half diagonally

Arrange units as shown below.

Multiples of this block make a very nice secondary pinwheel:

This unit that combines a quarter-square and half-square triangle is useful in any  number of blocks or designs.  Here's a wreath design, from Karen Krause at Kanesville Quilting, that uses the units both in the wreath and the bow.  Can you find the units?
