Red Heart Super Saver Yarn
It seems like the different colors have different "hefts"
I have been knitting squares that will be assembled into baby/toddler blankets, and some skeins/colors will yield 3+ squares and some skeins/colors yield not quite 3 squares.
I have a postal scale that can weigh in grams and my finished squares have turned out to be slightly different sizes (although each color is fairly consistent) and they do weigh more or less - depending on the color.
Just a heads up for anyone using this yarn.
I think my tension is fairly consistent - so I think it is the yarn that is causing the differences.
