Hello from Hey Grandma!
I had some time to spare before my two grand kidlets showed up, so thought I would make the second quilt block for the Sampler quilt, A Grateful Heart in the Winter edition of McCall Quilting Magazine 2009/2010. Back issue copies of this magazine can be found at http://www.quiltersvillage.com/
This block is called Peace and Plenty
Cut 1 square 7 1/4 cut diagonally twice creating 4 triangles.
From fabrics 2 and 3, which make the other two smaller triangles cut 2 squares 3 7/8 cut diagonally to make 2 triangles
From fabric 4, which will make make the larger triangles, cut 1 square 7 1/4 cut diagonally twice creating 4 triangles.
(I have found it is easier to get a better quilt block if you use a true 1/4 foot on your sewing machine) After your block is put together and pressed, trim it up to measure 12 1/2 inches.
If you were to make the four pinwheel blocks in the center out of one color (using 4 squares), this quilt block would be called Shaded Four Patch or Mary's Triangles Block .
