Is it difficult to restring a roman blind?

[Virgil]

The cords have snapped on two of mine and I'm wondering whether I should be able to restring them myself or whether its a case of taking them somewhere to be fixed?

I have just re-strung one of mine and it was a piece of piss. I bought some blind cord from John Lewis. If you are worried about what goes where take a photo, before you start, for reference.

It depends whether the cords are concealed in a mechanism at the top. If they're just looped through eyelets on the baton it should be straightforward. I've made several roman blinds, so would say that restringing them should be fairly simple.
