Prism, I did go back and read your reply. I found some good food for thought in your reply. I guess I have never tried such intricate patterns where the type of thread was that critical, and all the quilting classes I have taken, or seen on utube taught the pressing the same way. I didn't know that if one followed basic pressing principles, one could be pressing wrong.
There is a real upsurge in the number of people quilting again, younger people, older quilters restarting, etc. It seems as if the more standardization there is with directions and patterns, the easier it would be for people to be successful, learn correctly, and find quilting a fun, relaxing hobby, instead of making it more difficult.
