Here's a link for the type of markers I use: https://www.google.com/search?source=hp&ei=OkD1Xt3rNdDk-gT4_6GwDQ&q=chaco+chalk+roller+markers&oq=chaco+markers&gs_lcp=CgZwc3ktYWIQARgBMgYIABAWEB4yBggAEBYQHjoFCAA QsQM6AggAOgUIABCDAToICAAQFhAKEB5Q2akIWPemCWDo0wloA HAAeACAAaQCiAHBDJIBBTQuOC4xmAEAoAEBqgEHZ3dzLXdpeg&sclient=psy-ab. Although if you're marking the whole quilt you might want to mark only a few lines, sew those, then mark a few more, since they're chalk, it isn't permanent.
