Hi Debra. Yes that is correct. Each layer folds down over itself and that hides the seam. You could also just felt in along one end if you like that method better. I always start at the top and work my way down. You can cut it first before you felt it in, OR you can leave it long and cut it as you go.
You definitely have to be sure to brush the snarls out BEFORE felting it in. When you are done, take a large sewing needle and “comb” the fur so that you can trim it and groom it in the appropriate style for the breed. NEEDLE FELTED FUR CANNOT BE BRUSHED OR COMBED! It is felted in, not glued. Very gently “comb” it with a large sewing needle. DO NOT USE YOUR FELTING NEEDLE!! If you push on a felting needle SIDEWAYS they usually BREAK! TRIM off any loose hairs,,,do not pull out! If you are so kind as to give someone one of your felted sculptures, *be sure to include grooming instructions. You wouldn’t want someone to brush your gift and pull the fur out. Sometimes I can spend 30 minutes combing, trimming, shaping and grooming a long coated dog. The effort that you put into it will show!
