The Square in Square quilt block pattern is a very versatile one. In its basic form, the Square in Square looks exactly like its name. Another version set on point looks more like a diamond in square, but the block name is still the same. So is its construction.
Like so many quilt patterns, the Square in Square block is not made up of all squares, but does give the illusion of them. For instance, in the basic pattern, the center block is a four inch square.
Triangles are cut from a coordinating fabric, then sewn to each of the square’s four sides. So, the triangles create the illusion of a bigger square. More triangles from another fabric can be sewn around those sides to create an even larger quilt block.
It works the same with the on point version of this quilt block. A four inch square is the center block. It is turned to look like a diamond rather than a square. Add triangles to each side, then more triangles to those sides to create your quilt block.

If you plan to make the on point version of the Square on Square quilt block, you will be working with your fabric’s bias edges. Remember to work with your fabric pieces carefully so they won’t stretch or get warped as you work.
Like many quilt patterns, you can change the size of your center piece, in this case the square. Remember to calculate your needs carefully since you will be adding triangles to the edges and the blocks will become larger as you do this. Also, don’t forget to allow for sashing and borders.
To begin your Square in Square design, cut the square on the grain – lengthwise and crosswise. This will help control any stretch in your fabric.
If you are using a 4 inch square, your next set of outer triangles should measure 3 ½ inches on the two short sides and 4 ¾ inches on the long side. Taking the fabric grain into consideration, the triangles must be cut with the short sites on the straight and cross grain of the fabric. The long side of the triangle is cut on the bias.
Once you have sewn these triangles to the edges of your square, you technically have created a “Square in a Square.”
Many quilt block patterns, however, go a step beyond, creating yet another “square (so it is really a square in a square in a square).
To make the extended pattern, add another set of four triangles to your block. These triangles will need to be large enough to add to the outer block you just created. The short sides of the triangle need to be 4 ¾ inches and the long side will be 6 ¾ inches. Remember that the long edge of this outer triangle should be cut on your fabric’s bias.
The points of the triangles are the only “tricky” part of this block. It is important to line up each triangle with the center of the square. When your square and triangles are cut the correct size, there is really nothing difficult about this.

The Square in Square quilt block is a great, simple quilt block pattern on its own. Extending it by adding an outer square is a perfect way to enlarge the pattern. Depending on the fabrics you choose, the geometric shape of this pattern makes a great traditional or contemporary quilt. The Square in Square pattern is recognizable as a base in many other quilt blocks, such as Cats and Mice and Storm at Sea.
Placing a picture in the center square also adds interest to your quilt. These blocks have photos that are in keeping with the name of the block.
