I have used their embroidery sq designs...For the borders you have to cont. move the hoop after the section is done and line up correctly.
I have a Husqvarna SE with the endless hoop...and what happens is once the design is stitched out it marks a special stitch so after you move the fabric in the hoop it's lined up...Personally it takes forever and allot of patience. I did a pillowcase edge and haven't use it since...
