Ideas of using yarn remains

As I promised I want to share some found in the internet ideas (not my works) of how to use yarn remains.
As for me I really grudge throwing yarn remains out and now I have so many small clews that I even don't know where to keep them.
Recently I did a "revision" in my yarn stock and decided to get rid of all small clews I have.
I will use them to crochet kitchen tacks and nice small things just for fun. So soon I'll present my new trifle works.
And here are some ideas I like most of all.
I couldn't find the instructions to all pictures but some of them you can load from here for free.
