First off, you’ll need some supplies! This in itself takes some planning, as good quality materials will make everything go so much smoother. (literally)
As with anything else surrounding the custom world, there are good supplies and there are bad supplies. I started off using whatever I could get my hands on, but after Googling for hours, I found that other's weren't having near the hard time I was, and part of it came from experience, but part of it came from good supplies and good preparation as well!
