How to Make the Square in a Square Quilt Block

Join me again this year as I provide instructions for how to make a different quilt block each month. Eventually, all these blocks will turn into a great quilt! For the month of February, we are making the Square in a Square Quilt Block in this quick tutorial.  

Square in a Square Block

This is a fun block to make scrappy!

For a 12 inch finished block (12.5 inch unfinished), you will need to cut the following: 

Light Color (Centers)
- 4 of 4 3/4 x 4 3/4 inch squares

Dark Color

- 4 of 4 1/2 x 4 1/2 inch squares


- 4 of 4 1/2 x 4 1/2 inch squares

Cut out fabric squares in light blue, dark blue, and white


Start by cutting the 4 1/2 inch squares in half on the diagonal.

To create a reference line, press each of the center squares in half. Center the long side of a dark color triangle on the edge of the center square. The point of the triangle should line up with the crease. Sew in place, making sure not to stretch the seams. Press towards the triangles.

Repeat on all sides of the center square.

Trim each Square in a Square to 6 1/2 x 6 1/2 inches. Make sure to keep 1/4 inch away from the points of the center square.
