I have been making fleece sweaters from scarfs for a long time.I need to change them once a day and because we live in a colder climate i find it very economical to do this. One scarf will make three coats. Measure your dog around the middle and cut that from the scarf. I then fold it into a tube and sew. At the neck end i fold over about half an inch and sew around. Ican then thread a fine elastic through. You then fold your tube in half long ways. I cut about 4 inch square so the dogs legs will go through. You just need to slip this over the dogs head and his legs through the square. these coats are warm and wash great. I hope this helps get people started on a economical way to dress there chis.
