Today we’re going to cover a basic quilt block: the Diamond in a Square. The traditional way would have you cut a diamond and four triangle pieces, but we have an easier method for foolproof accuracy every time.To start, you will need five squares, one 5″ and four 2.75″. We used Wee Wander fabric for the focal square, with some of our coordinating scraps for the corners.
To scale this block to any size, decide how big you want the diamond from point-to-point (ex. 2″), then add .5″ for seam allowance (ex. 2.5″). Divide this by two, and add .25″ for seam allowance (ex. 1.5″). This is the size of your four smaller squares. So, the formula (Big Square+.5)/2 + .25 will tell you the size to cut the smaller squares for any size.On the wrong side of the smaller squares, draw a diagonal line.Place two squares right sides together on the big square with the lines cutting across opposite points, as shown below.Sew right along the diagonal lines on both squares.Trim the excess corner fabric with a 1/4″ seam on both squares.
Press corners open.Now, just repeat the same process on the other two corners.Press the block flat, and you are all done!
This block is great for showcasing your favorite prints. You can put a lot of them together in a snap for a quick quilt of any size. They also make great borders and filler blocks. We would love to see what you do with it!
