Improving Particle Board Furniture

Is there any way you could make a little curtain (fabric) to hang on the inside of the open part of the door? This would keep the dust out and could be washed a couple times a year. This way it would not matter what the inside of the cabinet looks like.

Same as what Deeli said, and this is not contact paper. You can lift and remove any time, re-adjust.

I would go to your local thrift shop and get some non-skid place mats. If they are square, you can save yourself some time. If the perfect ones are ovals, you can trim them down.
Good luck!

Rubbermaid makes really cool shelf lining that can be cut to fit, holds well to the surface and can we hand washed if needed. It's a thin foamy type lining that comes in assorted colors. You can purchase it just about anywhere including Wal-Mart, Target and even some pharmacies and grocery stores. It holds up just about forever.
