Bigmumma, all of the advice on this thread is good. I hope you find an idea or two that helps you.
I used to sew one seam every morning before I went to work. It was amazing how much I accomplished that way. (Then life changed and I changed my patterns.)
Let me ask you this: are you enjoying the process of washing and pressing your fabrics and organizing all your stuff? If so, you might want to let yourself off the hook a little, and stop feeling guilty for not actually making anything.
I find that I get as much pleasure from fondling my fabrics and looking at books as I get from actually working with them. And I remind myself that coin collectors don't spend the coins they collect, and stamp collectors don't use the stamps they collect to mail letters.
If you really would like to make something, then the advice in this thread about starting small is excellent. But if it's the process of collecting and organizing that you really love, then enjoy it without feeling like you "should" be "using" those materials. The point is to spend your time doing something that soothes your soul.
