Hemline Tailors Chalk
Four different coloured clay-based chalks in a small hard-plastic container with lid. Four colours per pack, white, blue, yellow and red. Use to mark solid lines on fabric. Brush off completely before applying heat or pressing with hot iron.
Removal of fabric markers varies on different fabrics. Always test on a scrap of your fabric to ensure easy removal. Do not iron or hot wash before removing chalk marks.
