Thin line helps positioning: When cutting, usually must mark on the fabric. The auxiliary line prevents pressure and double work: for larger sewing items and smaller items (such as sewing masks), the markers can provide direction at the seam. One box is suitable for all fabric colors: Bright tailor chalk white and yellow are perfect for dark fabrics. Red and blue are perfect for your light fabric. The texture of the tailor's chalk allows you to draw thin lines without much pressure. The tailor's chalk is removed, they just need to brush it off before washing. Because each fabric is different, it is still recommended that you provide samples of fabric residues. Tips: If the tailors chalk pencil is tilted a little while marking, the obtuse angle will be delayed or even prevented. A sharpener or knife quickly sharpens the chalk again.
