This is a wonderful marking tool by Clover. It is filled with chalk and has a tiny wheel inside that rotates as you move it across the fabric to leave a fine chalk line. Good for straight lines and curved lines.
Chaco Liner by Clover can be used to draw fine lines of chalk powder with a tiny metal wheel. Excellent for quickly and easily marking fabric in sewing, especially when using dark fabrics. Chalk can be washed from fabric when no longer needed.
