Here you can see the Before and After pictures of the lace I dyed.
I am very pleased with the results. I used Procion dye from Dharma Trading, and did it in the washing machine. It took me several hours last night, and I ended up washing it numerous times after it was dyed, to remove all the excess dye. I think I'm finally done with that, and I love the color. The color I used was Sage Green.
I'm ready to begin 'auditioning' things to use as an underlayer, and as Els suggested, silk organza is first on my list of possibles, and I have some loden organza that may be the perfect color.
I have a lot of colored organza, as at one time I was sort of planning to try to copy a technique I'd seen that had a dress with a doubled organza skirt (fold at the bottom.) It had organza shapes within the skirt in various colors. It was very pretty, and looked a little like an underwater scene. I collected colored organza in a desultory fashion for a while, and the mood seemed to pass before I tried it. I still think it would be fun to use it for something, probably something much smaller in scale.
Even though I love the results of the dyeing process, I am not eager to do it again. It was a lot of anxiety about the result, along with worry about using somewhat toxic stuff in my home. If I'd been able to do it in a bucket, it might have been less worrisome, but I knew the lace wouldn't have room enough to move freely, and the washer was my only choice, and actually was probably a lot less mess than anything else would have been. I have to say if I have to dye something again, I will probably chicken out and use Rit. Before this, the only thing I'd dyed for quite a while were lingerie findings, and I saved my old crock-pot to use for this in future. It has a Teflon interior that was beginning to flake off, but I don't think that would matter with dye, since Teflon is non-reactive.
I did have a birthday recently, and I wouldn't normally say anything about it, but I got the most darling little Birthday Sewing Bird from my mother, and I had to share him with you. He stands by my computer and I smile whenever I see him, he's just so cute and silly.
