Cut one simple paper snowflake from a folded square
Start with two folds and a few shallow cuts. Open the paper slowly to see the repeated pattern before making another.
You do not need a template or a whole window of decorations to try a paper snowflake. Start with one square of ordinary thin paper. Two folds make four layers for an adult to cut together. The finished shape is a paper decoration; there is no need to make it look like a particular snowflake outside.
Find the corner where the folds meet
Fold the square in half into a rectangle, then fold that rectangle in half into a smaller square. Press each crease on the table. Find the corner where the two folded edges meet. Keep that corner intact so the middle of the opened decoration stays connected.
An adult can make the folds while the child points to the folded and open edges. Before cutting, open and refold once if the edges are hard to identify. Use paper the scissors can cut comfortably through four layers; a thick greeting card is not a useful first choice.
Make only a few shallow cuts
Cut a small triangular notch from one edge, well away from the fold-intersection corner. Make a second shallow notch on another edge. Leave wide stretches of paper between them. You can trim the outer open corner to soften the outline, but do not cut a line right across the folded square or remove the protected middle corner.
Two notches are enough for the first reveal. An adult handles the cutting if needed; the child can choose which edge gets the next notch. Clear away the cut scraps before opening the paper so they do not look like missing pieces you need to fit back in.
Unfold one layer at a time
Put the scissors down. Open the most recent fold, then the first one, easing apart any layers caught on a cut edge. Lay the result flat and show where the same cut appears in more than one place. If a section tore, the remaining shape can still be used as a small decoration or attached to a contrasting sheet.
Hold it against a plain background to see the openings. For display, attach it to a larger piece of paper or let an adult choose a suitable removable fixing. You can stop with one snowflake. For a second attempt, change just one notch and compare the result; you do not need a more complicated pattern each time.
