Much easier than graph paper and much cheaper than EQ, is to copy photos of the quilt blocks you like and save them to your computer (there are a ton of websites with small sample images). Then copy and paste the ones you are considering using to Excel (or Publisher if you have it). You can then make more copies of the ones you want to use, move them around, turn them on point, whatever you like. It's like having a mini design wall with whatever blocks you want available.
Publisher will let you group all the blocks into one unit and save that as a jpeg file that you can then print out.
