I finished my latest Scrap Blanket. All of the yarn but the Aran color (off white, creamy color) came out of my yarn stash.
There are 63 squares (9 high by 7 wide).
The colored squares were made first. Then the Aran was worked around them and joined as I went.
The outside border was worked with all the little balls of the scrap yarn I had left over. I just started with one color and worked it all in then added another color, and so on. I ended up getting 5 rows of border out of it and had one little tiny ball of yarn left over which went into the trash. It wasn't even 2 feet long.
By the way, I didn't use any specific pattern for the squares. I just made a basic granny square and went from there.
