I made this completely out of stash yarn, scraps of acrylic baby yarn that's been sitting around. I started with the pink, then ran out of my little ball only to find out it was a different dye lot than the other 2.5 skeins of pink yarn in my stash. That's when I switched to white. I am actually very happy with the results.
I don't know exactly how much I used up on this sweater, but I'm calling it 273.1 yards based on my ravelry stash totals.
