There are 2 types of pattern repeat on a patterned fabric, Horizontal and Vertical. We are generally more interested in the vertical pattern repeat when making curtains and blinds and if only one pattern repeat is given by a manufacturer we would expect it to be the vertical one.
VERTICAL PATTERN REPEAT
The distance up or down the fabric, the pattern repeats itself.
HORIZONTAL PATTERN REPEAT
The distance across the fabric, the pattern repeats itself.
Hi, could you explain how I would work out how much fabric is needed if my blind is 191cm wide and 125cm drop. My pattern repeat is 37cm. I would like 2 seams (rather then 1 in the middle)as reading from your other messages this would look better. Thank you
The new tutorials are only covering single drops of fabric. We will be adding wide blind information. In the mean time If you look at the Lined or Interlined Roman blind tutorials there are links to the old tutorials that give you information on the wide blind calculations.
