Blockalogue: Square in a Square Block Tutorial

Please note that the following is not intended as a standalone tutorial. It has been written to complement the free PDF pattern available for download in my Craftsy store (Square in a Square Block Pattern). You will need the PDF to get the most out of this tutorial.

Square in a Square Block

The Square in a Square block, also known as the Economy Block, is a beautifully versatile block and one of my personal favourites. It can be made to any size and easily jazzed up, or down, through solid or patterned fabrics, applique, embroidery, fussy cutting, or even through traditionally piecing the centre square.

Cutting Tips
While writing the PDF, I made a test block for each size using the measurements specified in the Cutting Instructions. It was definitely possible to make the blocks correctly, but it didn't leave much room for error. A slightly inaccurate seam allowance and I had troubles trimming the block neatly. This is why I recommend cutting the inner and outer border squares larger than what is listed. I would increase the size from anywhere between 1/4'' to one full inch larger depending on your experience and confidence. Yes, you will use a bit more fabric, but you'll be grateful when you have a beautifully squared, perfectly sized block rather than the skewed, distorted mess I ended up with (no, I'm not sharing a photo of that one haha).

The centre square, however, should not be made larger. It is the guide you will use when trimming your blocks and must be correct.

Piecing Tips
This block is surprisingly fast to piece but care must be taken if you want great results.

Cut your inner and outer border squares into triangles. You will now be working with a bias cut, the diagonal, that can easily be stretched. Handle these pieces carefully. A quick starch and press may make them a little easier to manage.

Border Triangles

Find the centre point for you centre square and border triangles.

Find the centre of the centre square

Find the centre of the triangle

Match the centre square centre point with an inner border triangle, right sides together. Sew using a 1/4'' seam.

Match the centre points

Repeat for the opposite side. Press the seams towards the inner border.

Add the bottom triangle

Repeat for the remaining sides.

Attach remaining inner border triangles

Trim the block to size. This is much easier if you have cut your border squares larger as you will have more wiggle room. It is hugely important that you make sure that each of the centre square points has a 1/4'' seam allowance above it. If they don't, you risk losing your lovely points when you add the next border.

Trim the inner border, ensuring there is a 1/4'' seam allowance above each point.

Repeat the previous steps to add the outer border. Take care when sewing to keep the points on your centre square.

Trim the outer border to size, ensuring there is a 1/4'' seam allowance above each of the inner border points.

Finished Square in Square block

The finished Square in a Square block is just fantastic. It can be used in a quilt, pin cushion, table runner, cushion cover or just about anything. It's as magnificent on it's own as it is in a quilt.
