Checking "facts" like "the oldest American-made quilt" is often a piece of cake. It's too easy to debunk such competitive stories. Ten years ago we had a lot of fun with an Ebay post of the piece above, the "Oldest Known Quilt in Western World, with a buy-it-now price of $3,200,000.
Well, sometimes it's not a piece of cake, it's more like arugula soup; you hate to serve up a bitter concoction, but.....
Here we have a 45" wide fragment of a whole cloth bedcover allegedly cut from the oldest quilt made in what would become the United States, allegedly made in Boston by Sarah Kemble Knight. It's not date-inscribed but the caption lists an estimated date of 1682. We also read that it's silk with a wool batting. Is this the back or the front? The other side looks to be dark blue.
"The 1682 quilt in the Alabama book attributed to Sarah Kemble Knight is clearly very old, and without examining it in person I can't say for sure if it could be what it's purported to be----but after studying New England's early whole-cloth wool quilts for more than 20 years, from the design I would say that it dates no earlier than the mid-18th century...[likely] the second quarter of the 19th century."
"I've seen several New England or New York wholecloth [quilts] from this period and that large tulip-Like central motif was popular then. Michigan State University has a beautiful indigo wholecloth with the tulip central motif. I am thinking the possible dates on the Alabama wholecloth ought to be 1820s-40s."
