What I did was, I sew from the arm pits of the sweater around the collar area to the other side of the armpit area and made sort of circle which includes the arms. I stuff from the arms all the way around the collar are and arms then stitch the arms at the wrist area. The I stuff the chest area of the sweater real good then I stitched the bottom of the sweater. With a big needle I sew the bottom and all around the chest of the sweater to the bottom of the arms. Which makes a nice circle when sewn together. Your beagle will love it. Use something you have worn. It will have your smell and she will be happy.
