That's how many I'd have to make if I were to work swatches for all the color combinations of my Alv yarn. I was asked by a customer to advise her in choosing colors for the Truck vest. I loved being asked, but I did find this task a bit difficult, so I decided to make the swatches so she could see for herself. I thought 15 was enough, though. Here are additional photos of the blues, the greens, the reds and the purples (click for larger photos):
I do think there are some pretty ones amongst them. What's your favorite?
