It all depends on your style. I use a special page for every page of my blocking script. The actual page of the script is on the right side of the page while this sheet is on the left, if that makes sense. This special page, which I call my Script Notes Sheet, has special places for blocking, costume notes, props notes, scenic notes, etc. I have never had to transfer a script over into Microsoft Word, but if I did, then I would go ahead and write some of this information into the script notes sheet. For this specific example, I would split it up. For example, I would put the costume notes on the Script Notes Sheet, and then put the blocking directions and character information (the talking rapidly) in the actual script. This way you can know what's going on/what's supposed to happen during a rehearsal, and it will be right in the script. Then, when you have Production Meetings or your director mentions costume notes, you have all of the costume notes for that page on the opposite side, yet it isn't taking up space in your actual blocking script. If you prefer to not use something similar to a Script Notes Sheet, I would at least make a running list of costume notes/scenic notes/etc. found in the script. As I said before, it's all a matter of choice and how you want to do things. Best of Luck!
