In this short video David Procyshyn shows you how to make your own yoga bolster out of blankets. Bolsters and other tools are commonly provided to students by yoga studios and are used in a variety of positions and exercises. They are similar to body pillows, but are more firm and therefore provide more support. They are commonly circular or rectangular in shape. If you don't own one, and don't feel you will use one often enough to justify buying a bolster for your home practice, follow this quick and easy guide.
