The free pattern was intended for a pot holder, but why not make a throw/afghan with it? I did.
This is how I join my squares, in strips, then I join the strips together.
The end result is perfect for a baby throw,I made this for my soon to be born grand son.
You can find the free pattern here, as it is from a deleted web site, the way back machine has supplied the link, some browsers do not support the way back machine, so I suggest to use fire fox.
I used 8 ply yarn (dk) and the squares measured approx 6x6.
