I like the following to recommend for beginning supplies. Plenty of lively debate coming, so strap in boys n' girls.
Cutting board
Steel ruler (6" or 15cm ish is a good start)
Bone knife (as is found in sewing supplies for curving, scoring, creasing)
Xacto Knife, with lots of blades ... you should be replacing several during your build
Elmer's white glue and fast drying super glue
tooth picks to apply and smooth glue'
Card stock or board to laminate supports and inner structure
and ... paper.
