I have had more than one Moda red bleed.
I've also had RJR fabrics bleed. (Years ago)
I've also had a red that I purchased at a LQS this winter have excess dye.
I am in the group that feels - strongly - that it is just easier to soak, wash, and dry everything washable before cutting it for peace of mind, if nothing else.
I "assume" that whoever will be the final owner of the item will probably just toss the item in the wash and not be aware of the "proper protocol" for washing quilted items and I want to make this as foolproof as possible.
I do, however, fear bleach, burns, and tears.
