I like to change the banner out every month- that means I need something quick and easy to put together. Ever since one of my HEAVY cement topiaries was stolen right off the porch in broad daylight, the "fancier" banners don't hang there.
It really doesn't get any easier than this- pick a paper that's got lots of pretty detail and basically, all the work is done for you already!
I always stick to the same size 'flags' (the triangular-shaped pieces) and assembly is a piece of cake. Punch holes at the top edge of each chipboard flag and tie together with ribbon.
To pretty up the bottom point, I used pearl-headed pins threaded with a couple beads...
and that's all there is to it!
