Flat woven white linen tape, expensive, but the closest we have found to original 18th century tapes. It does not have a hard edge like the dutch tapes most of us have been using. Right now we have two sizes, 3/8 and 1 inch. Use the 3/8 inch for cap ties, apron and petticoat ties, and the larger 1 inch for hem facings, taping shirt and shirt sleeves. Price is by the yard. Half bleach is available in 1 inch only.
