Left and right symmetrical paper-cutting method of paper-cutting works "a hundred years of good luck"

1. Preparation: take four pieces of color paper, divided into two parts, folded once from the middle, stapled.

2. Tracing: take the pattern of the paper-cutting pattern, use a ruler to draw a straight line from the line of symmetry (the center line), find out the side of the folded paper on the stapled paper (i.e., the side that is connected) aligned with the line of symmetry of the pattern, and only draw the figure of the line of symmetry on the side of the pattern, that is, only half of the original pattern is drawn.

3. cut: left and right symmetry cut, the key is to deal with the folded side of the connection. If you cut a semicircle, unfolding will become a full circle; if you cut a diagonal line, unfolding will appear a folded line; so, cut the left and right symmetrical paper-cutting, you should take into account the effect of the unfolding of the cut, and do not blindly cut the connecting lines, resulting in the left and right separation, the graphic mess.
