If

IF you wanted to have some fall decorations on the wall
and IF you wanted to make a quilt that had lots of triangles in it, like this;IF you wanted to only work on fall quilts in October which means you could not possibly finish in one year... (this is the second year I have not worked on my 2 fall quilts in the fall...no guilt here though)
You could sew all the triangles together like this;and hang them on the wall. Who knows; you could use the 'banner' year after year with no guilt for an unfinished project....
Of course I did not do this, but I could have. These are not fall colors but they do look pretty on the wall of our dull apartment.
