My newest crochet project!

I'm going to be attemtpting this afghan in blue and yellow for my cousin's son. I was going to do one similar to ones my Mama did for us all but I can't remember exactly what they looked like and my mother, altho she has found them, hasn't brought my sister's afghans over for me to check out so i can match up patterns. I'm pretty sure it's a pattern from her crochet book but I have to verify it by sight. I"m very very excited!
