The sun is exactly the reason they are there
@justpottering. You can be blinded by the sun if you are sitting at the kitchen table so we can just drop the blind we need. That and the fact that it is a wide expanse of black at night, so blinds make it much cosier. Not needed for warmth as there is a conservatory on the other side of the window.
@Fiona M. Not a beginners project but just need a bit of practice really. Most important is making sure that everything is square as you move through the processes, of which there are many in this type of blind. I.e. the type where you cannot see any stitching on the right side. Lots of hand sewing.
Thanks for all your nice comments. Need to decorate now. I always do things the wrong was round.
