This wonderful counterpane was handwoven on a broad loom.  A secondary weft thread was lifted with a hook in the weaving process to create "knops" , small loops used to create the desired pattern.  This distinguishes Bolton counterpanes from other types of white coverlets.  This particular piece has a center medallion with a variety of borders.  Most of these counterpanes were made in England for export.  This is likely English and is woven cotton circa 1800-1830.  The symbols in the corner at first look like they are the date "1812".  But that is not the case.  The first two symbols indicated the maker.  The middle initial was either an "F" for Fine, an "S" for Supe Fine or an "X" for Extra Fine.  The last two indicated the size.  93 inches by 103 inches.
