Today I am quilting very long diagonal lines across the log cabin quilt that I'm making for DH, using blue painter's tape, and a walking foot on my Bernina (old model 830). On a rest break now because my shoulders hurt.
I saw a picture of a "manly" quilt done completely in single direction, diagonal lines that I got my heart set on doing. Right now I'm questioning my sanity! Keeping that sucker pinned and rolled up on the bias is a challenge, as is stitching. There are no landmarks to keep the lines straight.
I'm quilting every inch, so I found that if I use 1 inch painter's tape every other line, it is adequate. The alternate times I use the measuring guide on the walking foot set for one inch.
Cross my fingers, no pleats on the back yet, but I do have some wobbles in my lines from shoving the bulk of the quilt around.
