Basic paper crafting doesn’t need much more than a pair of scissors and your design, drawn or ideally printed on it so that you can carefully cut it out and add glue to stick it together.
As you progress in paper craft, your models become more precise and will have finer detail to deal with. I suggest the following items for good, neat and tidy paper craft models:
A Craft knife or scalpel for perfect cuts
Cocktail sticks are ideal for applying glue and aren’t as messy as a brush
Matt photo paper is great for pliability and prints much brighter colours than basic or cheaper paper
PVA glue is safe, strong, dries clear and dries fast.
A steel rule is used for a perfect straight line. Plastic and wooden rulers are too soft and you could cut into the ruler and ruin it and your work.
Scissors are useful for cutting out larger waste paper pieces.
Tweezers are good for picking up small pieces and will even help with creating smaller folds.
