Thanks GingerK for sharing this!
As you said, this could be a game changer, at times.
I was looking at a HST pattern the other day, and I can see doing this as an endless Leader/Ender project til I had miles of them together. Enough to make a quilt?
CashsMom ... I'm like you, and see the lines as a necessity to keep things in line (pun intended!) Though I noticed the different colours, straight and angled on her clear table. I think that would help us all go lineless and not even need
GingerK's painter tape method. Bad me ... I have been known to take a sharpie and actually draw a line on my sewing machine bed! (mostly I have done that after I put some protective tape down

)
