Back in the 70s when we lived in RI, I was still doing a lot of sewing and needlework. I made clothing for the children and myself, and even my mother. Somehow we found the Hamilton Web Company which made fabric tapes and edgings. I have been unable to find out if the factory is still there. I know it was bought by another company at some point, but don't know if the other company sold off the equipment or if it is still there. The present day meaning of Web has changed since the 70s
What to buy: They had a place at the factory where we could buy odds and ends yardage of the various fabrics.
What to pay: priced by the foot - different prices for different widths and complexity
