I started with EQ4 and have continually upgraded to EQ7. I don't use it as much as I would like. However, I am a computer programmer and I sit at the computer all day. So the last thing I want to do when I get home is to set at a computer again. However, I am proficient enought to create quilt layouts and make/adjust blocks already in the block library to create a quilt design. I have not mastered drawing (applique) nor have I yet mastered a quilt design with non-standard blocks (i.e. multiple blocks with different sizes). I find that the fabric calculation is not always accurate (at least in the older versions) but I can calculate yardage on my own. I like having it and enjoy having the quilt design as I work on the quilt.
