I read a mystery that had knitters in it, working on something called entrelac. I know there is another entrelac thread by cherinec5, but I'm not very good yet at replies with photos, so I thought I'd start from "scratch", so to speak.
This is a baby blanket I just finished. Someone else had posted photoes of an entrelac pattern with varying stitches rather than color changes, so I found this very soft variegated baby yarn and alternated pattern stitches with stockinette. The blanket is about 20" x 23".
I got the instructions from a book I have; since then, I've seen the link posted by cherinec5 (Good work, by the way!). The method I learned starts the foundation row differently, but otherwise it is worked the same. My foundation row had six triangles (the 20" side).
Anyway, here are pics.
