I think my template is the 7" one. But I use a VERY generous seam. I usually flat out use a 1/2" seam, but did go a bit smaller for this one, since I wasn't sure if it would still curve well with a wide seam. I think the finished square worked out to be about 6".
The quilt pictured on the template package was done in purple/blue batiks, and it was VERY pretty.
