I decided to try dying a few things with Dylon's Flamingo Pink machine dye.
from left to right
natural linen, was quite a dark tan (darker when wet) now more of a plum wine
yellow knit and yellow woven cotton, these have come out hot pink
plain white silk scarf blanks, these have come out flamingo pink as per the packet
peach broderie anglaise, this has picked up a little of the pink and therefore must be a polycotton with a lot of poly
isn't it interesting what happens when you dye things....
