Bird cage covers help your bird sleep soundly by helping to block light and cold air. Covers also act as a signal to birds, telling them that it's time for sleep. You can avoid buying a bird cage cover by creating an easy and cost-effective, home-made version of the same product. You will need to choose your fabric based on the climate of your bird's surroundings at night.
Measure the dimensions of the bird cage. Record the measurement of the entire base. Note the slope or angle of the top, if the shape differs from a simple quadrilateral one.
Add 2 inches to the base area of the cage and cut a large piece of fabric using that measurement as the width. Use the height of the cage as the vertical measurement. You will use this to wrap around all sides of the cage.
Cut a top piece into the appropriate shape to cover the top of the cage so that it will fit cleanly with the larger piece of fabric when you sew them together. You will have to add 1/4-inch to each side of the shape so that it fits accurately with the larger fabric shape.
Measure halfway down the width of the larger piece and make a small mark. Do the same with the piece for the top of the cage. Line up the marks so that the top piece of the fabric is centred with the larger piece.
Sew the top piece onto the bigger piece, folding the fabric as you sew to create a three-dimensional shape. Finish when you have sewn along the edges of the top piece, and the two sides of the larger fabric have come together. The long slit down the middle will serve as the opening for the cage.
Attach or sew Velcro strips or a Zipper down the sides of the open slit if you want the option of securely closing the cover.
Hemming the bottom of your fabric will keep your bird from getting stuck on lose fabric strings.
