Nobody wants to pay for anything ever. Fact.
That alone, can easily mess up the economy because some players will reduce prices so much that others cannot compete and it's completely unreasonable. I've come up with a few things I think should be brought into consideration when pricing items you've made:
1. Amount of coin for all materials
2. Skill level of the character
3. Quality of final product
4. The amount of time put into the craft itself
5. Simply the fact you can create the item when others cannot. (This goes for more difficult and higher level items)
Now I know that the game gives you the items worth when you hover over it...but I'm confused as to what that actually means. When I look at a badly made ruby ring it says 42 silver. When I hover over a perfect ruby ring it still says 42 silver. This leads me to believe that the "worth" is dependent on - The item and what was used to make it. Not the quality at all. It's also hard to go by the merchant's prices because the items you recieve are of average quality. So obviously a player that can make better quality items would have a higher price. That just leaves the question on how much to raise it, without being ridiculously low or high.
Of course some characters would rather trade materials and that seems like the best way to go honestly. Both parties get a better deal that way. However, if someone was to simply bring my character the materials needed, I'd still charge them something for the fact I -can- make the item. Labor shouldn't be free

Which brings me to cooking and baking. That must be the toughest craft to calculate. The simple fact that a cook can feed themselves, makes it possible for them to charge the bare minimal and think it's okay because the character is basically breaking even aside from a few tools.
I don't mean to give anyone more work, but I think everyone is a bit lost on how to price crafting out. I don't expect a full list on how much things should be, that would be ridiculous. Perhaps just a bit of an idea of how to go about it. I think if the players are left to it, the game's economy will fall once again. I don't want to be the one to ruin goldsmithing prices and set the bar so others can unreasonably compete just to make a sale. I know others feel the same exact way about their crafts.
