I forgot to say a few things about the pattern I posted yesterday.
- You can change the way it looks by making the corners : (2 DC, ch 1, 2 DC ) instead of (2 DC, c2, 2 DC ).
- It also works well as a one color square.
- Another option is to make a round or two using a variegated or ombre yarn.
- Another idea is to make a round of SCs with your choice of corners. ( see #1 above. )
