We just brought home our new puppy Pilot two weeks ago and the first thing we had to do was get a bed for him to spend his days on. Being that he's just a puppy, we opted for a less green bed that was chew resistant but would last a long time. Once he's older, however, a greener DIY pet bed from recycled materials (read: old bedding, stained clothing, unwanted jeans) would work wonderfully.
Fun in the Making has proposed and actually created a pet bed using reclaimed fabric. Using some second hand curtains, Hester Burch put together this great tutorial on how she made a pet bed using simple batt construction.
Beginning with two squares of fabric taken from second hand curtains and preforming some basic sewing, Hester put together the "case" for the bed. Here, she stuffed the tunnels with soft recycled fiber stuffing (made from industrial textile waste), but a few other stuffing options could include stuffing from an old pillow, scrap fabric pieces, or even old clothes shredded with scissors.
