Tips for Challenge models
Use bigger, thinner paper
15cm の紙では、細い足や頭がつぶれます。24cm 以上の、うすい紙がおすすめ。ホイル紙（裏にアルミのある紙）は形がよく残ります。
15 cm paper is too small for thin legs. Try 24 cm or larger, thin paper. Foil paper holds its shape well.
Pre-crease everything
「折りたたむ」ステップは、先に山・谷の折りすじを全部つけておくと、紙が自分から形になります。迷ったら一度開いて、折りすじを確かめましょう。
Before a collapse, put in every mountain and valley crease. The paper will almost fold itself.
Go slowly where it is thick
何枚も重なった所は、一度にぎゅっと折らず、内側の層から少しずつ。中わり折りは、先に谷折りで折りすじをつけてから中へ入れます。
Where many layers stack up, fold the inner layers first, a little at a time. For a reverse fold, pre-crease it as a valley fold first.
A failed model is a great teacher
うまくいかなかった紙を開くと、折りすじの地図（展開図）が見えます。作品ページの「練習用紙」と見くらべると、どこがずれたかがわかります。
Unfold a failed model and you will see a map of creases (a crease pattern). Compare it with the practice sheet on the model page.
