Fine Motor Skills

I am trying to find a developmental timeline for where a three year old should be with his/her fine motor skills.Does anyone know a website or have information on this? Is there a standard or does it depend more on the child's developmental stage? While I am not specifically concerned about Delaney's FM skills, I was feeling I haven't worked with her enough in this area and want to make sure I am having her do the correct kind of fine motor actvities for her age. (4 in Feb.) She is pretty much right on target and/or advanced developmentally, but I dont' want to skip any important basics she should do. Thanks for any tips!
