Ideas for Unique Cache Containers

Lately I have been unable to cache nearly as much as I would want to so I have had time to begin thinking about when and where to hide our next cache. Now, I say I have had time to do it, but it does not mean I have done that much as far as making progress is concerned. There are a few things I am sure of that must occur in our next hide. First off, I want to probably make it a micro because we have yet to hide one of those. Next, I want this hide to be fairly tricky for even the veterans to find quickly which also makes a good case for it to be a micro. In thinking about this much it has occurred to me that in order for it to be genuinely tough I will need to think of the perfect cache container to place. There are numerous routes I can take in approaching this as well. Basically, the first step for us is to decide on an area for the next hide so I can search out the surroundings and assess what kind of micro will blend in the best and cause some trouble for the finder. Here is my dilemma though; should I buy a pre-made container or build one with the numerous materials available? I think it would be more unique to build my own but then I look at the ones online and they look so elaborate and perfect that I am tempted to buy those. I am really at odds about this one because I am afraid that I could not build a good enough micro to satisfy my urge to have a cache that is actually very tough to find. I guess I am trying to find out feedback from people who have hidden pre-made ones versus built their own. I have found both and they seem equally hard to find if done right. It looks like I am going to be thinking about this up until we find the place to hide it which at this rate may be awhile.
