Has anyone found the diagram and instructions lacking for this pattern? The Chart only shows 2 color contrast, I see 4 colors in the pattern. Black, White, Brown, and Tan. Why does the pattern chart not show all 4 colors? I am going to have to create a better chart on graph paper in order to explain and have a good example of a design for students to follow. This is not the only pattern I have found rather short on description - knowing that most of our students are newbees - the better the pattern the easier for them to follow. Example - I completely wrote out - row by row - the Mitered patchwork blanket - my student said that was the only way she would have been able to follow the instructions as the Craft Yarn Council pattern was limited. Thanks, Janis
