Pet beds can be quite expensive, but with some creative thinking, an old sweatshirt, and a used pillow, you can create your own.

Start by turning a sweatshirt inside out, grab the edges of the collar and sew them together with a thread. Leave a piece open and turn the sweatshirt right side out.
Sew the sweatshirt armpit to armpit in a straight line across. Stretch the sleeves along the body of the sweatshirt and sew them to the sweatshirt.
Now, stuff the sleeves with stuffing or old clothing until they’re full, and use the hole you left in the collar to pull the stuffing to fill the sweatshirt. Then, fill the belly of the shirt with a pillow and sew the bottom and the top of the sweatshirt shut.
The last part is to sew the cuffs together.
