You can probably find them at Vermont Country Store. They were an acrylic, also dried fast. I still have four of them that were wedding presents in 1962. Have just put new satin binding on them. We've lived in FL almost 45 years, no doubt the reason they lasted so long. Nine months of the year, a sheet is all that's needed. :-)
