I remember reading once that the color royal purple was, anciently, derived from mollusks, and that it took something like 10,000 of them to produce a pound’s worth of dye; hence, the only people who could afford it was royalty. We, in our day, being able to buy clothing of any color whatsoever, have no idea how privileged we are. I’m sure one could overdye indigo on top of brick-red madder root–and I have seen ancient Egyptian cloth that still had a touch of madder redness to it, thousands of years later–and get a brownish-tinged variant. But a true purple would have been vanishingly rare. (There are natural dyers out there who know far more on the whole subject than I.)
There are artisans in South America who still go to the shore, gather sea snails, squeeze the purple out of them, and then put them back. It washes out of their cloth to a soft lavendar over time, I am told.
At Stitches West a year ago, I bought a half pound hank of Lisa Souza’s handdyed alpaca laceweight dyed in Shade Garden, a soft purple/green/blue mix. I dyed some Misti baby alpaca laceweight in lilac last fall and knitted the two strands together into Kristine’s shawl; recently I took some light blue merino lace yarn to the rest of the hank and made the second one shown here.
I put it on, after blocking it, and felt like royalty indeed wearing Lisa’s work.
