ctom Is right start out with small steps and progress as time goes by. for me I had no one to teach me anything about plastics it was trial and error for quite a while it took me a couple years to learn the basics and we are still learning but you will learn very fast my only if you have questions please get on here and ask. I did not see start out with a hand pours I directly started with injection molding which is the best way to go be careful it is very addictive.
