I think it is inevitable that light-colored canvas gets yellow and the print fades in time. Just like the white multicolor items from a decade ago. I would still use my watercolor bag and SLGs without hesitation. Afterall it is a sign that the items are well loved and well usedWell it doesn't bother me and it's really subtle so I'll let it slide. I don't think the store will have a solution either; I guess it's just how the material ages. I'm interested to see what it looks like in a year.
