I wasn't sure which orange thread I used that caused the bleed on Carpe Diem. So, I set up an experiment to find the culprit.
I took the four likely suspects and put some of their thread onto some white Kona, some light grey Kona and the Taupe/Grey Artisan Cotton that was used in the quilt. I added water and waited.
And none of them bled.
I am baffled as to why that thread ran.
