Hancock's Marking Wax Crayons
Made in Dorset by Hancock’s, these wax crayons are traditionally used for marking worsted wool cloth. They are more solid and feel smoother to apply than chalk, leaving a more resilient mark. This can be removed with steam pressing (use a cloth to protect the cloth and iron) but do test beforehand, especially on lighter fabrics.
Available in black, red, blue, yellow and white.
Price is per crayon.
