ROLLER BLINDS - SEAMS

Seams for wider blinds

Where a blind is wider than the fabric specified a seam may be necessary.

Seams must always run horizontally so we will first 'rail-road' the fabric ( turn it sideways) so that the width of the blind becomes the drop.

RAILROADING FABRIC WILL CAUSE VERTICALLY STRIPED FABRICS TO RUN HORIZONTALLY AND MAY DISTORT PATTERNED FABRICS SO THAT THEY ARE UNACCEPTABLE TO THE CLIENT

If the blind is shorter than the width of the blind ( less a few centimetres for turnings etc) then there may be no seam. However if the blind is longer - say 2.5m drop with a fabric that is only 2m wide then two pieces of fabric will need to be joined together and there will be a seam approx 2m from the bottom of the blind.

The seam is always positioned towards the top of the blind - which means that it is out of sight if the blind is lowered by less than the width of the fabric used.

We need to leave around 20-30cm of fabric on the barrel of a roller blind in order to create tension and ensure that the fabric remains insitu. So where a blind has a similiar drop to the width of the fabric used, there will be a seam that sits on the barrel. Whilst it is largely invisible the doubling of the fabric on the seam can cause a rippling effect on the fabric that is rolled over it
