I used a variegated acrylic yarn, it took 250 gms of yarn to make.
The Tank is made with hdc, the pattern I used is called the Preppy Tank from Crochet Today Sept/Oct 2007. It is made a little on the loose side to wear in Spring and Summer with a singlet top underneath. I found it a tad too short, so I added a fringe to give it a little more length.
I really like the stitch pattern used at the top of the tank.
I'm already onto my next Spring/Summer top, it's a project I wanted to do last year.
