How to age cloth to finish antique quilt
I have received some 50 year old quilt piecing. Most of it is finished and ready to sew but a couple of the pieces need to be finished with white cloth. I found some cotton cloth that has the right weave and feel as the original cloth. However, I realized the older piecing has gotten slightly yellow with age. How do I dye the new cloth to be a smidge yellower without messing up the quilt?
I am worried about dying it with a light tea mix as I'm not sure if it will bleed onto the other piecing when washed.
Thank you all for any advice you may have.
