How do you mark your quilts before quilting? When hand quilting I really like the purple pen with disappearing marks.
This little table runner is all Easter egg colors so the purple shows up nicely. And it fades quickly so I only mark part of the project as I go.
On dark fabrics I have a white pen that erases easily with a damp cloth. I've also used masking tape for straight line quilting. I only hand quilt small projects because I have a short attention span - or at least that is my current excuse.
