I use stencils and Crayola Fine Line Ultra-Clean Washable Markers! The lines all wash out! I will use a white chalk marker on darker fabrics. I put a free motion quilting foot on my Brother 1500 and enjoy following the lines. If I go off the line a time or two, that is okay! Once it is washed, no one can see the small errors! I use Superior Thread Mono Poly Invisible Thread, except on my borders when I want the design to show.
