I'm thinking of making a pair of lined curtains, but I don't quite follow the construction. I've been reading the guide to making them on Channel 4's website. The bit that confuses me is how you attach curtains rings to the heading tape - what is the device or product that goes in between? There aren't any hook style curtains in this flat to refer to and I just can't visualize how they go together.
Also, if anyone knows any good online guides to making lined curtains, that would be really helpful!
