The exterior
Almost any material will work for the bag. A material that has a grip-like surface helps prevent the camera from sliding during use. The material from an old koozie works because its design makes it slip-free and water-resistant. Use thinner koozies to make the bag as flexible as possible. Cut the material so that when it's folded it makes the desired bag size. If using koozies, cut them straight down one side and across the bottom and place one flat on top of the other. Align the edges of the material and trim away any excess if required. Line up or fold the material inside out to keep the seams on the inside of the bag pod.
Construction
Sew around three sides of the beanpod. Use nylon thread to add sturdiness to the seams. At this point, it's time to fill the pod with the desired material. A variety of materials exist for filling the beanpod---beans, rice, sand and even bubble wrap. Rice makes an efficient filling. The grains have the right size to conform to almost any surface and it gives the bag just enough weight to keep it steady. Fill the bag almost completely with the chosen material. Do not overfill or the bag will not retain its ability to change shape. Sew the remaining opening closed. A strap makes carrying the bag easier. Cut two strips of material about 1 ½ inches wide and to the desired length. Place one on top of the other and sew together. Sew the strap to the existing seam of the bag. Use multiple passes with the needle and thread to make certain the strap has a secure connection to the bag.
In use
Use the camera beanpod almost anywhere. Want to get low in the garden for flower shots? Set the beanpod on the ground and nestle the camera in its shape. Looking for a different perspective? Place the bean pod in a flowerpot or on top of the doghouse, nestle in the camera and shoot.
