This portable pet carrier is easy to make and doesn't cost a lot in materials. The mesh top is removable so the basket can be used for an outing or at home as a pet bed.
Fold a plastic tablecloth in half and lay it on your workspace. Place the basket upside down on top of the tablecloth and use a pen to mark the size of the basket on the tablecloth. Cut the tablecloth (double-sided) at least 3 inches larger than the marking to allow for the seam and stuffing. Sew the two pieces together almost all the way; leave an opening to add the stuffing. Then sew that last piece together.
Cut a piece of screen material large enough to go over the basket handles and halfway down the sides of the basket. Cut the corners the shape of the basket. Sew a seam all the way around the material large enough to allow the elastic to slide through. Leave a small section open to straight pulling the elastic through with a safety pin.
