I make a lot of anchor charts. Actually, one of my goals this year is to have almost no store-bought posters on my wall. Not only will this "look better," but I'm hoping the kids will actually refer to them because I made it with their specific needs in mind. I love the fat, chiseled Sharpies, but they bleed through the paper I find Sharpie's chart markers don't stay, well, sharp very long! However, the ink does seem to last a long time. Are there any other great brands out there?
