I had Quilt Wizard for a while and used it a lot. I recently upgraded to EQ6 and it's excellent - the block and fabric libraries are really comprehensive plus you can download updates, import images of your own fabrics, draw and design your own blocks, etc, etc. It figures yardage for you but it DOES overestimate. For example, if you have a pattern that uses HSTs, it'll figure a whole square of fabric for each HST, rather than assuming you'll get two from one square. You can also print out PP patterns, draw and print appliqué templates, etc, etc... The only thing I would say is it does take a little investment of time to learn how to use it to it's full capability. :-D
PS Plus now I have 'E-WIPs' - in other words, stuff I've designed but not got round to making yet... :mrgreen:
