Some things to keep in mind:
There are lots of factors that play into the final size of an item. I've listed approximate sizes for this reason. Some yarns are thicker than others, which will create a slightly larger finished piece than an item made with a thinner yarn.
Prices vary depending on the complexity or material cost. An item covered in 'additional pieces' such as the Ice Cream design or Garden design will be more expensive than those without.
I do not do custom orders or commissions, I am sorry.
