These two are variations from the book Three Dozen and One Bookmarks, although I didn't like the final round so I changed it a bit.
The yellow and white one below is also from that book. The rainbow-colored one is a variation on the Mile-A-Minute ones above, just with a different edge treatment.
These next two are the "Quickie Bookmark" from Priscilla Hewitt, which can be found here.
I've really enjoyed these quick projects. Now I just have to decide which ones go to DD's teacher and which go to the teacher's aid. I was hoping to deliver these tomorrow, but I won't have my act together by then. Thursday is the last day of school so I'm running out of time....
