WIP - Shell-Stitch Cardigan

Yarn: unknown white Acrylic
Hook: I
This pattern is from a Columbia-Minerva "Learn to Crochet" booklet (also from, you guessed it--the rummage) . The pictured cardigan is in a light blue and looks more attractive than my white version is turning out to be--but there was a gap in my wardrobe for a white cardigan and not a blue one? (Also I had the white yarn :)
