I'm using Cold Reactive Dye thickened with Manutex. I started using the sponge brush but found the roller faster.
I layed the lace out onto plastic shower curtains and started rolling.
You need to apply a bit of pressure so that the colour penetrates right through.
Then hang it to dry. It drips just like normal dyeing so make sure that there is something to catch the drips underneath.
This is the tea rose. Once the lace is dry it need to be heat set. I'm going to try some multi coloured lace next. Just need to wait for the hanging space to be available.
