How are steam items supposed to work? Craft them in game?

How are the steam items supposed to work? You should be able to craft any item in your Steam inventory in game?

I have 4 items, but I can’t craft any. Am I doing something wrong? Is it just not working yet?

And, if I sell the items then I won’t be able to craft those any more? So people sell duplicates and items they don’t care about?

Wow, no one actually knows this?

Yeah, you can sell duplicates of items on the market. And you should be able to craft the ones you have in game, though I have heard of others not being able to. It must just be a bug at this stage. Look for them in your clothing tab.
