This pattern is from Leisure Arts "Afghans For All Seasons-Book 3", copyright 2002.
Pattern name is "Carnival" page 64.
This pattern shows specific colors, but I like using up scraps when I make this. Makes a very snuggly blanket despite the 'open weave' of the stitches. Super simple pattern. Great for beginners. You can probably still find the book on Amazon or EBay!
