Can I ask opinions on where to situate the vertical join for a long, deep Roman blind, please? The total width is 175cm, drop 208cm. Either side of this one will be two narrower blinds, same drop, 84cm width. My fabric is 138cm, exc. selvedge.
The fabric is patterned and so the join won't be as obvious on a plain fabric, but I can't decide whether to go asymmetric (in which case I can squeeze another narrow blind from the offcut) or dead centre. The blinds will be lined by blackout fabric so the seam won't be backlit from the windows. My instinct is telling me dead centre, but I need a bit of moral support on this one, please, ladies!
