I found this website tonight and thought it would be a good one to share with other quilters out there. You can resize and print many types of graph papers, as well as save a copy of them for future use. They come up as .pdf files, which require a free download of Adobe Acrobat (if you do not already have that on your computer.)
I am planning to use some of them in my little notebook for sketching quilt designs. This will make it a lot easier for me when I do not have to draw out the shapes myself, but rather can just color the graph papers.
Check it out for these styles of graph paper:
Moorish (like a windowpane design)
Guitar Tabs (for you, Steve and Matt)
Hope this is useful to you!
