Use a single sheet of standard letter or A4 paper
Fold the paper lengthwise in half, then unfold it
Fold the top two corners down to the center crease
Fold the new top edges down again to the center crease
Fold the plane in half along the center crease
Make the wings by folding each side down evenly
Keep the wings narrow for better distance
Add small upward wing flaps at the back for stability
Make all folds sharp and symmetrical
Use a slightly heavier paper for longer flights
Throw it straight and level with a firm smooth motion
Aim slightly upward, not straight down or too high
Test and adjust wing angles for better glide
Add a tiny bit of weight to the nose if it stalls
Reduce drag by keeping folds tight and edges aligned
