Here is a fun home project that takes about 30 minutes.
Take a cola crate..
Cute you some 2" foam to size. Make sure that it is not so snug that you can not fit it in the crate.
Pick out some material that you prefer, and sew 3 sides. fit your foam in it, then sew your last end. I made a pillow also...
I leaned down to take a close up pic for you, and my baby girl jumped in it.
PERFECT doggie bed!!!
