Make small crochet figures. I made them about 5 cm. long.
Sew the back of a pressure button onto the back of each figure.
Sew the other half of the pressure button onto a T-shirt, making sure they are placed the right way to fit the half you placed on the figures. I used five, arranged in a circle.
I had nine figures and only five buttons on the shirt. You can keep the figures in a small pouch or fun little box.
Voilà! This is what the T-shirt looks like. The user can decide how to combine the figures, and for washing figures can be removed.
