Making the color block band

1. Make the band

Cut a piece of fabric that measures 3 x 25 inches. This band will be placed on the front bodice piece of the t-shirt. I’m going for a v-shape look, as pictured above. 

Measuring the fold

To prepare the band, fold it in half, right sides together. Then, determine how prominent you want the v-shape to be. 

At the fold, measure 1.5 inches from the top. You can mark between 1.5 inches to 2 inches, but not less. Otherwise, the v-shape will look more like a curve. 

Drawing a diagonal line

Once marked, draw a diagonal line, starting from the top mark to the folded bottom point. 

Sewing along the line

Now, sew on this line to secure it. 

Trimming the excess fabric

Trim off the excess fabric and open up the seams.

As you can see, I have a really lovely v-shape for my DIY color block shirt. 

Folding and pressing the edges

Next, fold in and iron ½ cm (0.2 inches) all along the band's edges. This just makes it easier to sew along the front piece. 

Tip: Take your time while ironing, especially when you get to the middle of the band. It can be a bit tricky to fold in sometimes. 

Pressing the front of the shirt to find the center

2. Attach the band

Fold the front piece of your shirt in half and give it a good press. Like this, you have a crisp center crease as a guide.  

Placing the color block piece in the center

Open the front piece right sides up and place the band on top. Make sure the center of the band matches the center line of the shirt. 

Marking the center

Mark the center as needed so you have a reference when moving the band. Remember, you want everything as straight as possible, so feel free to wriggle the band around. 

Ensuring that the V is evenly placed

Ensure that you have the exact same measurements on each armhole.

Once you’re satisfied with this, secure the band with pins to prevent it from moving around. 

Where to sew a topstitch

Sew along the edges with a topstitch using a 1mm (0.04 inches) seam allowance. 

Trimming the excess fabric

3. Trim the excess fabric

Once complete, remove the pins and trim off the excess fabric. To do this, turn the front piece over to the wrong side. Cut and shape the trim along the armhole’s line.

All done! I’m really happy with how it turned out. All that’s left is to continue assembling the rest of the pieces for your shirt or leave it as is if you adding the V to an existing shirt.
