It's a pretty simple pattern to copy. The blocks have only two components: big half-square-triangles and little half-square triangles. (HST = half-square triangle) I'd guess that the big HSTs are 6"x6" (finished) and that the little HSTs are 2"x2" (finished).
To construct a block:
1) sew a big HST
2) sew 16 little HSTs
3) sew three HSTs into a strip, repeat
4) sew one strip onto one side of the big HST and other strip on the opposite side
5) sew 5 HSTs into a strip, repeat
6) sew one strip onto one side of the big HST and other strip on the opposite side
The quilt shown has the blocks set on point - the big blue triangles are the setting triangles. The size quilt you want determines how many blocks (and setting triangles) you need to make your quilt.
If you're new to quilting, I suggest making a test block with any fabric you have handy. Some people enjoy working with HSTs, and some people find working with lots of small ones aggravating. There are lots of different methods for making HSTs. I prefer using a method where I cut the fabric a little bit large and then trim down after the parts are sewn together.
