Let's start with the opening.
Pull the two straps together.
You will have the star in your hand.
I didn't put a pearl or clip into the envelope,
it might have damaged it...
Perhaps you don't see it well, but i clippted the two
straps together, than tied a knot and lengthened the star
with a satin ribbon as desired.
I attached it on a hook by the window frame.
P.S.: I wasn't sure if everybody was able to see the meaning of the Star and Mick suggested i should give you a instruction of the build together, not rather the hole making off...
