I have a question regarding making these for the humane society here where we live. I have their permission, and crate sizes. I also have alot of flannel and fleece I bought on sale for them. I have alot of cotton scraps I can use too. My question is for those that have done this, do you just make them like a receiving blanket, and secure the edges, or do you use 2 layers of material? The Executive Director, said she would rather have the blankets for the crates, colorful ones, I guess for the attention of people looking for a small pet. I also am going to make some for the large dogs, that are not in crates. She said I could if I want to, but said it doesn't get cold in there. I know all the concrete and ceramic tiles, has to be cold on them. Thanks for any help...and if anyone has photos, they would be much appreciated if you would post them.
