I made these garlands a couple weeks ago. It was so easy and affordable I have to share.  I started out by painting white poster board (more like paper)  with a watered down light grey,  the original white was a very unnatural stark chaulky white.  Next I screen printed some geometric images in a very very light grey- looks more like a soft white.  You can also just hand paint or make some potato stamps to achieve this as well.  Next I cut the paper into strips,  then into little triangles.  I sewed them all together leaving long threads at the top end.  I found a pretty old branch in the yard (actually I think this branch is one  I found somewhere on the coast and drove it with a few others all the way back home)  Any branch or dowel will do!   Tie the top ends and voila!  A pretty thing you can use as a screen to hide something or turn into a mobile.
