Clover Chaco Pen liner - Blue Quilt Marker - Refillable - Patchwork & Quilting

Pen Style Chaco Liners fine point permits accurate drawing of both straight lines and free hand curves. The fine point makes lines and marks more visible and is easy to use with a straight edge ruler. Easy replacement refill available

By far the best fabric marker out there. Unlike normal tailor's marking chalk or chalk pencils, I don't have to shave off the ends or sharpen the pen. The lines are always thin but perfectly visible.
