I’ve just discovered the iron blanket
It’s a piece of cloth you simmer in a solution of water and ferrous sulphate for about an hour or so and you use it as the outermost layer of an eco print (or botanical pressure print, if you like). It helps transfer the colour from the plant matter you’re using, onto the fabric or paper you are printing onto. In the process, the print also prints like in these photos, onto the blanket. I found the technique on Facebook’s Eco-Dyeing, Creating Learning group, which I just joined.
I wrapped this iron blanket round several layers of silk habotai, organza and muslin into which I bundled plant matter from my garden and local woods and also, some leaves from three different types of Eucalyptus leaves. The euc is thanks to my two local florists. In this photo, the earthy red circle in the middle is a print from a green euc leaf.
The cloth was still wet and crinkled when I took these photos.
Here’s one with some of the plant matter still attached after steaming then undoing the bundles. It’s a piece of fern leaf, from the garden.
And yet another. The cloth is an offcut from an Ikea curtain that was too long. It’s heavy-duty 100% cotton.
