I love machine dye! A box of dye, a bag of salt and no messing. Sometimes I use it to tart up faded old tops, or if I find something in a charity shop which fits well but is a boring colour.
The ones above were originally a grey t-shirt with pastel heart print, a white t-shirt with red floral print and a white shirt with a black print (the stitching stayed white so must have been polyester).
I used Dylon Machine in Flamingo Pink. All these items in this post went in together, but took up different levels of colour according to their fabric content (highest natural content gives deepest colour).
I had two identical white M&S bras, but one them went grey when I acccidently put it in the wash with my jeans, so as I was dyeing the other things pink anyway I thought I'd throw it in rather than binning it. I didn't expect it to take the dye as it's polyamide (manmade, I assume) but it came out pretty well - free new pink bra!
I got this old tray cloth and a lace-trimmed antimacassar from a charity shop...
...and they came out beautilfully! The tray cloth was linen and that really soaked up the colour. After I'd had them lying around for a couple of days I realised they reminded me of Pearl Lowe's lace curtains. I'm so pleased with them, I'm going to find some more and try them in different bright dyes.
