Here is my makeshift still life studio I made in my room. (notice the lint roller holding the muslin up at the top) This can be done with any dark sheet, material or if you are wanting a white background, use a posterboard or large sheet of paper. Paper is better for white b/c it will bounce the light.
Here is the finished product
It was fun to play with the light b/c the same feather appears to be different colors depending on the angle of the light.
