Bias binding is a cotton hem which you can opt to have sewn along the edge of your tablecloth. Bias binding isn’t necessary as the PVC or Teflon coating does seal the edges to prevent fraying. However, bias binding gives a ‘finished’ look and adds to the presentation of the tablecloth. You can choose it as an Optional Extra when you buy your tablecloth. If you require a specific colour for the bias binding please contact us with your order number once you have placed the order. If we don't hear from you we will choose a colour which blends in with the overall tone of your tablecloth. Bias binding is cotton and not PVC coated. Please note this option is only available with oilcloth and teflon coated designs. Tablecloths with bias binding will come with slightly rounded corners.
