I got all 15 right!!! Thanks to all the wonderful information shared here.

12 right, and I would have had one more if I hadn't clicked the continue button so fast. I realized in the instant that I clicked what the actual right answer was, and it was too late.

10... Some I had no idea.... oh well.

12 I never can figure out that warp and whatever thing. Bias is on the angle and cut the borders the way the yardage goes not with the selvage edge is all I remember.
