Hi Barbara
No opinion on QP but I use - and like - EQ7. QP has a rep for being more user friendly and it is less expensive. Have you checked the QP website - they have a free 30 day trial which might help you make a decision. EQ is strictly a quilt design program - it does not tell you how to piece or quilt. I think that is true of QP also. Maybe OzarksGma can chime in on that.
Check Softexpressions - there is a lot of info on various software programs. There used to be a lot of reviews, but I don't know if that is still available.
Re general information on piecing and quilting - there is just a ton online, and that is how I learned to quilt. That is, of course, assuming that you have a reliable and affordable internet connection. For books, check Better World Books or
Abe Books - both have a big selection of used quilting books at good prices.
I am sure you will be happy with whatever decision you make - quilt designs programs are fun.
