Could you die the lace to match the dress material?
That is a possibility. The trick is to get the right shade. I’ve found that different fabric materials such as cotton, linen, silk or polyester, take the dye differently. So, even if I used a matching white fabric for the dress and white thread for the lace, and dye them at the same time in the same bath, it doesn’t always mean that they’ll come out the same. I haven’t done enough dyeing to know how to control it, just enough to have had bad experiences.
Are the professional services which could do the job for me?
