WIP Wednesday: The Never-ending Afghan

A very wise person once said, "I may not be there yet, but I'm closer than I was yesterday." He or she was obviously talking about making an afghan. Obviously.

Good News: all the squares are complete.

Bad News: Because of the design that I chose, I have to make 28 granny triangles.

 Further Bad News:  I then need to connect them ALL together. Every last one of them. 141 pieces.

141! Right now (unless any of YOU have a better idea), I plan on using this method as demonstrated by Attic24. If I don't run screaming into the night first. 141 pieces. what was I thinking?

What's the biggest project like this that you've ever done?
