Fabric and threads are dyed with MDX Procion Dyes and with reasonable care are permanent and colorfast. I have rinsed and soaked them multiple times in hot water to remove excess dye. However, the fabric and threads may still have some residual dye that can migrate.
It is always good practice to wash lights and darks separately. If you are making a project with very light and very dark fabrics, I recommend washing in cold water.
If any dye migration happens, it is most likely to occur when wet fabric or threads are allowed to lay on white or light colored fabrics.
