I know this is over a year old...but I found it when I was trying to find an answer (will post that shortly).
I'm only a beginner...never done a quilt, just made small projects like table runners, muffin baskets, pot holders, that sort of thing.
But, I took the quiz of 15 questions, and to my surprise, I got 13 of 15 right. I guess it goes to show what a lot of reading books can do, as well as read a lot in this forum.
So...on to my question in the next topic called combining rectangles and triangles.
