Since we are tackling granny triangles this week, here’s a very dear project to me – a granny triangle collar. And I cannot believe I made this a decade ago! 
I don’t have the pattern for this, because I worked it on a whim (it happens a lot with me!), but I am reconsidering making another flowery one. 
So making a collar is an interesting way to use triangles, and I also dug into internet to find other examples of their use aside from buntings, but to my dismay, there were so little projects it’s truly sad the triangles are overshadowed by the traditional granny square. 
Below I added imaginative use of triangles for bags and hangings (the last ones could be transformed into pouches, paper weights or door stoppers).
