What to buy, what to use?

There are always choices and decisions to be made and making decor for dances is not an exception. Getting ideas and concepts sometimes originates in my head and many times I browse Internet to see what is going on and what other people already did. Visiting local craft stores let me buy many things and I do make many pictures of things to buy in the future. Here is a collection of stuff I saw and/or bought for my projects. I am about to get more Valentine's gadgets and what to choose?
