i think that some fabrics printed at the height of various trends tend to look pretty dated 20 years out. i am thinking of sea foam and peach florals from the 80's, orange, brown and yellow poly prints from the 60's - that kind of thing.
other fabrics - notably calicos, ginghams and plaids - tend to age so much more gracefully. i still love to look of 30's prints and colourways. others must too, because of the vast number of reproductions printed every year.
when i see these teal and pink quilts, or orange, or yellow and grey combos, i tend to think we'll view them as very dated in no long time. i tend to stick with more traditional colourways, both with an eye to the future and based on personal preference.
