DYLON Fabric Dyes for hand use are perfectly suited for smaller items like shorts, vests or socks, and for delicates you'd rather not put in the machine like wool and silk. You have a rainbow of beautiful colours to choose from, and whether you're refreshing an army of black socks or want an uplifting hit of colour with vibrant tights you can be sure of beautiful colour and permanent results you'll be happy to show off! Don't forget, for effective dyeing you'll need to add salt (see instructions for details). Pack contains 50g and will dye up to 250g fabric to full shade or larger amounts to a lighter shade. Suitable for Cotton, linen and viscose. Lighter shades will be achieved on wool, silk, polyester/cotton & polyester/vicose mixes.
