Colors change in each lot, and sometimes even in each skein. If you want to avoid problems you should combine skeins as you knit. Oh, and try to buy all the skeins you need for your project in one order, the differences between dyeing lots are usually evident.
Every monitor shows colors in a slightly different way, and even though I take a lot of care when I edit the photos, what you see on screen will never be exactly what you see in the real skein. Also, the photos you see on the page are usually not of the same skeins that I am going to send you, although discreet, there are always some variations.
Lava la pieza terminada con cuidado a mano y en agua fría (NO TIBIA!!!), y con el mismo champú que usas para tu pelo. No necesitas usar vinagre. En los primeros lavados se puede soltar un poco de tinte, así que si vas a usar colores muy contrastados es mejor tejer una pequeña muestra y lavarla. Esto es imposible de evitar, así que lo repetiré mil veces si hace falta: lavar a mano con agua fría y champú!

A menos que se indique el contrario, los precios son por madeja.
