The Shadow Box Quilting Block
The unit above uses value with the dark and light side. See how this looks when the blocks are grouped at the bottom.
This is a very easy and frugal block to piece. It is a 4 patch. The large block takes up 3 of the patches. Using simple measurements, and having each grid finish at 2 inches, you cut the large square 6 1/2 inches raw.
You cut the vertical rectangle 2 1/2 x 6 1/2 inches raw. Then you sew these units together.
The bottom unit is cut the width of the block - 2 1/2 x 8 1/2 inches raw. Then a small square, 2 1/2 x 2 1/2 raw, is attached to the corner, sewn on the diagonal and pressed back. It is the same technique used in making the flying geese block.
All that is left to do it sew the two units together. You can can use the color value differently for different effects, but all your blocks must be done the same. You can put the dark fabric on the top, bottom or side.
In the picture below a light colored 2 1/2 square is place on the left end of the black strip. Then it is folder over to make the diagonal line. You can get confused on the direction to sew the diagonal line, so baste one first and see how it looks. It is also important to get the piecing correct so that the corners line up correctly.
Note that there are other ways to make this block. This way is one is the easiest. Here is one effect you get when you use value with this block.
