My hints may have already been noted but here goes:
As I get a lot of my patterns from those who are gracious enough to share through websites and blogs, to keep track I have started a database that includes the following: website, pattern author, recommended needles and yarn, yarn and needles used (if different), and a photo of completed work. When written down it may seem time consuming but believe me it's come in very handy for me.
We all know how hard it is to pass up a good yarn sale, which results in a multitude of yarn skeins with no room to store. I now store mine in vacuum storage bags. Works great with wool and other natural fibers. Keeps it dry and I have stored about 30 skeins in a large bag.
