I’ve been saving avocado pits and skins for a number of months, but the contribution from a colleague (thanks, Rhonda!) far outweighed – literally – the amount that I got through over the summer.
The pits were halved, sliced, then either dried or frozen; the skins were ripped into smaller piece, then dried. The dye liquor was made by soaking the relevant parts in water, then adding either bicarb or ammonia, then steeping the cotton yarn in this for a few days.
The photo, as always, doesn’t really show the true colours, especially as we’re in autumn and the sky is overcast, but the bottom row were all attained by adding bicarb to draw out the red. The yarns all turned out various depths of pale pink.
With the two on top, the left was from 20g dried skins (purple ones) soaked for a few days, then for a few days more with ammonia, then a few more again with the yarn. In real life, it’s slightly darker.
The one on the right was from 100g frozen, sliced pits following the same method above. The ammonia definitely brings out a deeper shade.
Now, what to do with with five balls of cotton in antique pink? Actually, I’ve thought of one use, but that’ll have to wait.
