The Art Square quilt block looks incredibly simple to make. Just 3 shapes to cut.
You'll learn two different methods (one no-cost, one some-cost) to cut the center, on-point square perfectly.
You'll also see a neat way to use this block to showcase a collection of existing blocks. Looks complicated, but isn't—one of my favorite things.
If the name isn't familiar, you may also know the Art Square as:
Let's get started!
All seam allowances (SA) are 1/4". It helps to take this simple Sewing Test to make sure your's are perfect.
Starching your quilt fabric ahead of time will help tame the bias edges on the corner units.
Be sure that there is enough contrast between your fabrics.
While I'm happy with the sample block in person, the photos of it don't have enough contrast between my two fabric choices. (Another good reason to make a sample block before diving head first into a new quilt!)
The math for squares set on-point in blocks (like the #3 patch) can get a little wonky.
Many designers will have you cut the them 'just a bit bigger than' a standard rotary cut size or cut it '6-3/16 inch square'. I don't know about you, but my ruler is marked in 1/8" increments...not a 16th in sight.
Since we go to the trouble of fine-tuning our quarter inch seam, it seems kind of silly to me to then have you 'guesstimate' the size to cut the patch.
Therefore, I offer two alternative ways to accurately cut #3. The first is with the On-Point Ruler by Donna Lynn Thomas. The second is using a template which you can download below.
All the measurements in the chart below are for squares, i.e. 1-7/8" means cut a patch 1-7/8" x 1-7/8".

**Cut this patch with the On-Point Ruler. If you don't have this ruler, click here to print templates.
To use the On-Point ruler, line up the measurement with the cut edge of the fabric as shown below.
With right sides together (RST) align the edges of a #2 triangle to the #1 patch.
Stitch starting from the even side of the pair of patches—that way your machine won't 'eat' the points.
For accurate seams, use a stiletto (or in my case my handy seam ripper) to guide the points of the triangle straight through the machine.
If left unguided, they tend to pull to one side or the other.
This first #2 is just a smidge longer than the side of the #1. Don't worry—that's how it's supposed to be.
Add the second #2 to the adjacent side.
Again, start your stitching from the even side of the group of patches. Your stitching line should fall exactly in the valley of where the patches meet as shown below.
In this closeup of the backside of this corner unit, you can see how the first #2 extends a bit past the edge of #1 (lower right side of the light square) and how the second line of stitching bisects the valley between the patches (red arrow).
After pressing, the diagonal edge of this unit should be straight.
Repeat for the three remaining #1 squares.
Arrange the patches as shown below.
To find the center of each side of the #3 square, fold the square in half and fingerpress a crease (red arrow).
With RST match this crease to the point of the #1 square (arrows). The points of the #2s are longer than #3. I prefer to pin them to help keep everything lined up.
Use your stiletto (or seam ripper) to help guide those triangle points through your machine.
Stitch. Press SA toward #3.
Add the two remaining corner units in the same manner.
This is your finished Art Square Quilt Block!
Part of my system as I write these tutorials is to plop the blocks into several standard settings to see if it doesn't get the old creative juices flowing.
One of my 'go-to' placements is to use the block as a cornerstone with sashing.
This one, I think, is a winner!
The lights and darks of the original Art Square are switched. The #1 and #3 patches are now two different fabrics/colors.
Now plop the block into a cornerstone and this is the result.
To complete the design, you'll need sashing like this where the blue strips are 1 grid unit wide plus 1/2" and the cream strip is 2 grid units wide plus 1/2".
