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.
The measurements for my roman blind (recessed) are 1775mm for the width and the drop is 1158mm. I am therefore wondering how much fabric i would require as the blind is wider than the fabric - this is 137 cm wide with a fabric repeat of 32cm.
Thanks for the fantastic tips, you make it so much clearer than any other videos i have watched.
We haven't written the extra instructions for wide blinds yet. The fabric calculator HERE though does make the calculation for you. As you are using a patterned fabric you will need an adjusted cut drop (calculator will tell you), so you can join the pattern on the fabric panels. We never join the fabric down the middle of the blind, we always have a central width and join equal amounts to each side.
