Like many other crafters, I could not find what I wanted in stores, or I found it in a catalog, but it cost too much, and I said (repeat after me)
I can make that myself!
My dog, Finley is about 13 years old, and hasn't had a new dog bed since he first came to us nearly 8 years ago. His current bed has seen many slap-dash covers, and is mushed and scrunched so badly I can't imagine it provides any cushioning for his arthritic joints. I'd been looking in stores for a supportive bed with a removable/washable cover for a dog his size, and found only cheap beds filled with fiberfill (to meet the same fate as the current bed), or beds with no removable cover. L.L. Bean sells beautiful beds, but for a dog Finley's size (70lb), it would be well over $100.
Two weeks ago, I called an upholsterer, looking for foam scraps to stuff a bed. I was delighted to receive an entire couch-worth of cushions, intact. He couldn't reuse them (by law), so I picked them up for free!
Then, last week, DH spied the perfect fabric at JoAnn, and matched it with a coordinating stripey fabric. With my coupons and the sale prices on upholstery fabric, the entire bed came to $25.
Method: I cut off the one "wing" from the foam rectangle. I wrapped the foam in batting (leftover from previous project) to soften the top and edges. I made a removable, washable cover, piping all around the top/bottom edges by covering cord in bias tape. There's a zipper on the back. The construction is modeled after our Ikea couch covers. The zipper was a bitch. The piping was a bitch. Fortunately, I measured almost everything perfectly, and I'm quite pleased with the results.
Finley is, too. The blonde puppy trying to hone in on his new throne is Molly. She may be next to receive a custom bed as I still have more foam cushions left!!
I coax him onto the bed:
He actually lies down on it:
In situ, in our bedroom. The bed is meant to match our duvet/sheets as well as the rug in front of it:
