Like all products I've purchased so far from Wisdom, these printable PDFs have a multitude of uses. I've used the varying widths of lined paper to differentiate writing practice, the graph paper for art projects, and the dot grid for my own planning. Well worth the minimal cost!
We are a family of writers, gamers and doodlers, and love having access to the different grids and rulings, as well as the dots, whenever we need them, one sheet at a time. Now, instead of stockpiling the variety, I only need to make sure we have printer paper on hand!
