Yes, you can fake a DIY. You can fake it 'till you make it. Or just plain fake it.
Here are some great examples. First the fur chair. If you check my archives, I made one from simple fabric store fur. This one I love. You have 2 choices here, go to your fabric store and get some to just drape or staple, or even safety pin on a chair. Or, choice 2, the throws, yep, the throws with the furry undersides, they wash great, just throw over, pin or staple. My Walgreens, and my grocery store both have them at this time of year for super cheap. Ok, $15.00.
Now to the desk. Store bought (any big box or home improvement store), get a plank of melamine in the size you want and put on file cabinets, mine in my office are on old shelves from Target, they have 3 shelves, you build them for like $9.99. Be creative folks. Craigslist, Target, Big Box, Home Depot, Bueller, Bueller, Bueller.
