Coffeetables....

So I own the above plain Ikea coffee table.  I believe it cost $20.  I have the matching side table for $12.

Dear reader, I think you can understand why I chose said pieces of furniture.

However, they 'do' for now.

Recently, the 'Martha Stewart' in me thought I might 'do' something to them.  Such a paint or tile them.  Anyone out there know anything about bricolaging (or decoupaging?) a table?  Your thoughts?  Recommendations?  Suggestions?  New hobby ideas for me?
