I was wondering if I were to dye eyelet, would the stitching take the color or not? I think it would be a nice, dramatic effect to do pink, purple, green, orange, etc. with the white embroidery.

Dear Tracy,
Experiment and find out! If the eyelet is cotton and polyester, which most is, you will have a pale version of the dye color with white thread. In any event, it’s cheap enough to see what you get.
Have fun,
Jennifer
