I am currently working on finishing up a Mystery ghan that was hosted by Julie at Ravelry. You can see some of the squares in that slideshow above. I just finished clue #4 and now time to work on the final clue.
So I started out by drawing pictures of squares and then the symbols in them........then took a generic square I had and marked where I thought the design needed to be. My mother chose two colors for her afghan, Soft Sage and Shocking Pink.......both are from Red Heart, but have different feels to them. Soft Sage squares come out slightly smaller. Anyway, I did all the first squares with those two colors. I did not have to redo any of the squares.......although I did find a mistake in one of them, pattern was written right, I just made a mistake while working the square.
I hope you check out the link and join up. Please feel free to share this with your crochet friends.
