This colour card shows the whole Luca-S stranded cotton range, so shades can be compared with each other and against the fabric before ordering. It is a handy tool for anyone who stitches regularly, substitutes colours in a chart or puts together their own palettes rather than relying on colours seen on a screen.
You are buying the card only: the threads are sold separately. Look at it in daylight, which shows the difference between close shades far better, and keep it with your charts: alongside the solid colours it also covers the mélange and metallic mouliné, useful for sparkling details.
