Dabz - EQ7 is a fabulous computer program where you can make up your own designs and quilt blocks, It will tell you how much fabric you need, choose colors, print out templates for each block or save as a pdf, and more. The latest one out is EQ8, which does still more, but is a different format.
Here is the website - do watch the video.
