Material: card, 120gsm for small models, thicker for larger ones.
Scoring: any blunt point that's handy.
Cutting: Craft knife for edges, scissors for tabs (I use the single-tab method).
Glue: Bostik. It dries very quickly. Mostly, I spread a thin layer on each surface (using tip of tube and fingers), wait a sec to go tacky, then press together. Glue on fingers, being tacky, does not stick to paper
. After a while it builds up thick/dry enough to peel off easily. Where I need a little time to position something, I glob the stuff on and push it in place straight away, so I have a few seconds to slide things into place.
