How much would you pay or think this double knit babys crocheted blanket is worth?

[Yumi]

The cost of the materials used in the blanket. Adding the quality and time it took to make.

But by looking at it I'd say around $30-50. You want to make your money back from the cost of the materials at least. Without overcharging to the point that no one would consider purchasing it. So main point just charge more than the materials altogether cost you.
