Personally ... I wouldn't touch them until you know what you want to do with them. You'll kick yourself if you cut them into strips and find you need squares ... or whatever.
I was tempted for so long to just cut mine, but I resisted. Glad I did. I finally decided on the pattern I want to make from my "scrap heap" and I need 2" and 4" squares. I have another scrappy pattern on my bucket list that will use small narrow strips, so I'm saving the left overs from this scrap cut for the next project.
