One of the features of EQ7 that I love is the ability to make/design your own blocks. Makes it muh easier to adapt a quilt pattern that you have seen. I especialy like it when I am using a panel or something for a focus in a block. I can work around the size that I have rather than having to find a focus fabric that fits the premade quilt block size.
To me, EQ7 was worth the money. I have found a copy of EQ5 on Craig's List a while back. I loved it but was fustrated with its limitations. When EQ7 came out, I did a LOT of research and decided that it really fit my needs.
