I agree with everything posted about templates so far. However, I looked at the quilt and to me this seems like quite a difficult quilt to attempt with templates. Both cutting and piecing need to be very accurate in order to get all seams to match, plus it can be quite challenging to get all the points sewn together as neatly as in the photo. It is even more difficult because you are working with a lot of bias edges.
Personally, I would probably attempt this pattern only if I could die cut the pieces (or possibly piece by hand). At the very least, I would recommend heavily starching the fabric before cutting with the template pieces to help keep the bias edges from distorting.
