Diamonds in Squares

Here is one of my favorite ways to use up scraps.  Making a quilt with a diagonal set takes a lot more time than a regular quilt.  However, when you put sides on a square, it turns the square so that it is on point, and looks like a diamond. This gives the quilt more movement, and is as effective as a diagonal set.

There are many ways to use these blocks.  The snowball technique is easy, but uses more fabric.  See the snowball page for instructions. Below is the more traditional way to do it.

How to make the Diamond in a Square Quilt Block


Step 1:

This is a very easy block to make.  First determine what size you want to make your center squares.  Let's make this quilt with center squares that finish at 5 1/2 inches.  So the first step is cutting all your squares at 6x6 inches.


Step 2: 

Now you will add the triangles around the sides.  You will cut the 4 triangles from 2 large squares.  Take the finished size of the block, and add 1/4 inch to make the large squares.  Since the squares are finishing at 5 1/2 inches, add 1/4 inch to 5 1/2 inches.  Using precise measurements, your  squares would be cut at 5 3/4 inches.  However, cut them at 6 inches, as you are going to have to trim them anyway, and this way you have some wiggle room.  This block will be trimmed to 7 1/2 inches.

When you add the side triangles, add opposite sides first, and then trim.  Make sure the centers are even by finger pressing the triangle and square in half or using the iron.  After doing the first 2 sides, do the last 2 sides.  Press, and square up the block and you are done.

Last step: Trim block to final size.


In order to make sure your trimming is accurate, always be sure and put the 45 degree line on your quilting ruler one of the outside edges of the center block.  Then slide your ruler until you have the 1/4 inch seam allowance outside the points of the center square.

Your final match point is one of the horizontal or vertical lines on the ruler to one of the outside edges of the quilt block.  However, when you first begin trimming, the lines on the outside edge of the block will not be straight.

As a final note, when you make a scrappy quilt, try not to match your colors and patterns too closely, as in the illustrated instructions.  Notice how much better the blocks look at the top of the page where the colors and patterns are more varied.

Note:  It can be tricky to determine the final size of the block from the cut square.  Here is a table to give you a few standard measurements of finished quilt blocks.  Remember that you are always better off cutting a little larger, as you will be doing a lot of trimming.
