Here is Teresa's finished block. You can make it any size you want. Her tutorial on the block is on her blog. And is November 23, 2011.
After squaring up the strip she used darker stips to cover the raw sides on two sides. The starts adding different strings to make this odd looking block. The she squares the whole thing up.
What a stash scrap buster. You can use any size pieces and some odd sized pieces you wouldn't use anywhere else. Any color goes and it is found fabric in my estimation. You have paid for the fabric why not use it up instead of throwing it all away.
