I've told the company that I find it tricky, thus I wasn't sure I'd recommend the template for use with stationary machines, since this design can be done with other methods, but if you did a lot of this design, which is great for a cuddly quilt, you might find it an excellent help.
The closer to the center anchor point, the harder it is to use, but being able to use one template for this design is pretty awesome. If I were to use it, I'd start farther out from the center and if need be, use a different design to fill in the center.
For a frame mounted long arm, I bet this thing is awesome!
Now I'm off to go quilt on my ruler work sampler. I even have the new TopAnchor Celtic Knot template prototypes to play with. I can't wait to get these listed in the shop! I may offer them as a pre-sale option. I started this sampler for my Craftsy class, Quilting with Rulers on a Home Machine (25% off discount link there) and it is just ridiculous that I have yet to finish it!
By the way, I totally revamped the shop for easier navigation last week. I'd love to hear what you think of the new design.
