Waste not want not……

I was so pleased with my onion dyed hanks – I kept looking at them at thinking – Wow!!
Next day I was going to get rid of the remaining dye but when I had a look in the bath, I thought there might be some dye left. I had some hanks I had previously dyed with lichen, moss and nettles, but the colours were quite muted. What would happen if I over-dyed them with the remains of the onion dye? This would be over-dyeing and exhaust dyeing in one go. Over-dyeing as I was putting colour over an existing colour, and exhaust dyeing as I was using up any remaining dye in the bath.
So I thought I’d give it a go…….

I soaked the previously dyed hanks in rain water (it’s still raining here!!) and in the meantime added a handful of onion skins to the dye-bath, brought it to the boil and simmered for another hour. I drained the water off and I added the wool; I tied the hanks into knots to try get the ‘patchy’ affect – almost like tie-dyeing.I simmered the wool for an hour.
Here’s what I got!

Originally this wool had been dyed with nettles. It was a very pale green, as it had been the last batch in a previous nettle dye. The pale wool at the bottom of the picture is the original. When I over dyed it I got an orange/green tie dyed effect.

The next one had originally been dyed with lichen as an experiment. Unfortunately, in the lichen dyeing, the wool had taken up practically none of the dye, so the result from the over dyeing was a definite improvement.

The last one had originally been dyed with garden moss. Again the original dyed wool is at the bottom of the photo; another pale pastel green. Over dyeing gave it a definite orange colour.

I have to say I was quite pleased with the results. As there would have been some copper sulphate left in the dye-bath from the previous day, the colours were not overly bright, but they were good strong colours. In previous exhaust dyeing with onion skins, I had gotten bright yellows from the last dye bath.
The tie-dye effect creates a wonderful pattern in the wool when you make something with it.

I love exhaust dyeing; it’s a great way to get the most from your dye bath. From the 140g of onion skins I originally used I got a whole range of beautiful colours! And over-dyeing is a way of using previous disappointing dyes and improving on them.
