As you may have seen in previous posts I really like detachable collars. So after seeing this idea on Rookie I decided it would definitely be worth a try.
You'll need:
-an old collared shirt
-scissors
Lay the shirt out on a flat surface and cut along the dotted line as shown in the picture below.
You should be left with this.
Taadaa!
I also made this one.
They're super easy to make so why not give it a try yourself?
