I have looked at a few paper pieced Double Wedding Ring patterns (i.e. McCalls) but I am still afraid to try curved seams. I have located one on Paper Panache

It appears to have a less "rounded" look to it and am wondering if anyone has used this pattern. If so, would you please tell me if this pattern eliminates the need for curved seams.
