We say "acid-free" a LOT here at the museum, and we're very happy to share with you just how important that buzzword is for textiles. These bolts of fabric probably date to around the 1990's and are lovely shades of "Country Teal" and "Garden Green" - until they are unrolled. The photos show that where the fabric at the center of the bolts rested against the cardboard, it has been significantly discolored. Since some of our earliest quilts date back to 1980, imagine what they would look like now if we didn't take care to store them in the right materials!
