It's simple than less difficult than most people think, you simply put together whatever the amounts you want to consolidate in one address and make another transfer of all together to it or another one you control in your wallet, at least that's how I understand it, it's like melting small chunks of bitcoins down to one big chunk together. But you want to wait when transaction fees are cheap enough to do that just because the bitcoin network charges per the amount of data you are putting on the timechain the less data the cheaper.
