I hope you've gotten some help clauden. I do not have an endless hoop with my ellegante2 . with the endless designs I simply rehoop . *4U
I have the Pfaff endless hoop. I find it easier to draw a straight line on my fabric with a fabric marker. Then when I move the fabric I just make sure that line is always in the same place on the hoop. And with the precise positioning fuction it's a snap to line up the next section. I did a continuous run of FSL across the top of a queen size sheet and 2 pillowcases as a wedding gift. Don't want to do it again as it was very tedious, but it came out great. And was quite a hit with the happy couple.U get a * for effort.
I have Viking but have not used the endless hoop. I understand that while stitching out a section it places a marker on the fabric that you need to line up when moving the fabric.
