Here's an object lesson in dyelots:
Yarn: Brown Sheep Cotton Fleece
There are two different dyelots of Cotton Ball in this baby blanket, and since I was using up small squares and making new squares, the different dyelots aren't evenly distributed throughout the blanket. I just keep telling myself the baby won't care. A few washes and some baby grime may even it all out in the end, and it will be a project finished!
