Ikea FÖNSTERBLAD blind pergola connections

Blinds are expensive, and once I'd put my pergola up sun was coming through the sides so this needed a fix.  Ikea has super-cheap blinds so was able to get smaller blinds at a reasonable price to fit the gap where necessary.  The trouble was these flail about and I wanted them to act as a single unit.  This model includes two items - a bridge clip to keep the blind weights connected, and a variation of this bridge clip with a 90mm square clip to go around the pergola legs.  The result is these Ikea blinds pull down as one, and don't flap around like a car dealership inflatable wobbly man.
