The rayon fabric I am currently
The biggest challenge when overdyeing fabric that is colored or patterned is to figure out, at least theoretically, what color you will end up with in relation to what color or colors you start out with and what color dyestuff you use. At the very least, it requires great imaginative effort, for more accuracy, it requires sample dyeing. Rather than start by preparing several dyebaths, I decided to make a chart, and carefully think about how colors usually interact.
|#||FABRIC COLOR||OVERDYE BLUE||OVERDYE BROWN|
|1||black||no change||no change|
|2||dk grey||darker blue||darker brown|
|4||navy ||no change||slightly warmer|
|5||lt grey||darker dull blue||darker dull brown|
|6||dull blue-green||darker bluegreen||bronze brown|
|7||bright med blue||darker blue||cooler brown|
|8||periwinkle||darker cool blue||cooler brown|
|9||ice green ||slightly green blue||slightly bronze|
|11||warm cream||slightly warm blue||slightly warmer brown|
|12||lt grey||slightly darker dull blue||slightly darker dull brown|
|13||lt blue||no change||slightly cooler brown|
|14||pastel teal||slightly green blue||slightly cooler brown|
As I had suspected, the most challenging color in this print is the hot pink, which shows up often enough that whatever color it turns will be a noticeable accent color. I don't really like purple or terracotta very much. It is slightly more difficult to predict colors with brown, since brown is not a primary, or even a secondary color, but a mixture of red, yellow, and blue, often toned with either white or black as well.
I shall continue to mull over the possibilities. I found this exercise to be informative, as though my initial thought was to overdye in brown, but looking at the probable outcome, I am more inclined to go with the blue, as more of the shifted colors are ones that I am comfortable wearing, and are already in my wardrobe. Perhaps it is time for me to get over my irrational dislike of purple? In the interim, I shall get the pieces prepared to sew, and stitch together the new popover dress, a good task for another terribly hot day. If I stitch up the seams and topstitching in black, the thread color will not be a factor in the overdye process later on.
