If people are complaining about the $55 price tag, there's your answer. It's too high.
We as fellow crafters can not give a good unbiased opinion on the price because we ALL know how much work goes into making a blanket like that and are quick to quote a higher dollar amount. But we're also not the ones who would actually buy it, as we can make them ourselves.
The non-crafting customers are the ones who set the price because they will (and have) unabashedly tell you if the price is too high, too low, or just right. If they're complaining about $55, they're not going to pay it, so what's the point in pricing it that high? You have to find a balance between time spent and what someone will pay.
I'd drop the price to $40. See how it sells. If she gets a lot of enthusiastic sales quickly, raise it to $45. If she still doesn't see the sales, drop it to $35. The goal is to find a price where people will pay it, but not so low that the orders come so fast that she can't fill them.
Two blankets sold for $40 each is A LOT better than none at $55.
