So- this bag style was started in our Quilt Guild meeting. It is called a Pet Mesh Bag as the black part is made from Pet Mesh- a material made to cover a doorway or a pet carrier or pet play-yard. You can buy it at a Home Depot where they sell replacement screen materiel. I got the 48 x 84 inch roll about $20.00 for 6 bags. The construction is simple and it is fun to mix and match fabrics. The bottom has a hard piece of timtex, cardboard or foam core to give it more stability and form. I would estimate that it takes me about 2-3 hours to make one. That is not to bad I did not think. IT is very basic. These 2 both went to Baby Showers, I have one then I gave one to a friend in early Nov. and another to a co-worker for her birthday . . . so I have made 5 - they are quick and easy and look nice.
