2. Make sure the open end of the base is facing downward. Then, fold one of the sides into the middle, like so.
3. Use your finger to slightly open the fold.
4. Make a squash fold.
5. Repeat Steps 2 – 4 on the remaining three flaps of the square base.
6. Fold the sides of the top layer of paper inward, like so. Then, undo these folds.
7. Insert a finger into the space in the middle of the frog base and carefully begin to move it upward. This step is similar to completing Steps 5 and 6 of the crane base.
After you complete Step 7, your frog base should look like this. (Tip: It’s okay to be a little bit forcefully with the paper when trying to smooth out the top part of the interior diamond. I’ve also found that using my fingernail to strongly crease the upper corners of the interior diamond really helps to shape it correctly.)
8. Repeat Steps 6 and 7 on the remaining three squash-folded layers of paper, and your frog base is complete!
1. The crane base is actually developed from the square base. When your square base is finished, it should look like this. Make sure the open corner is facing you.
2. Fold the sides of the top layer into the center, like so.
3. Repeat Step 2 on the reverse side.
4. Fold the top triangle down. (I usually also fold it the same way on the reverse side to make a better crease.)
5. Unfold the paper back to the square base. There should now be three very pronounced crease lines on the paper. As shown, insert a finger into the opening at the bottom. Gently, begin to pull the bottom of the paper up toward the top.
6. Continue folding the bottom of the paper upwards, and flatten out one side at a time as you do so. (Tip: I’ve found that this step is much easier to accomplish if you do it while holding the paper in mid-air, rather than trying to keep it flat on a table.)
7. Flatten the other side of the paper so the paper looks like this. Repeat this step on the reverse side, and ta-da! You’ve made the crane base!
2. Fold the paper in half horizontally, then unfold.
3. Fold the paper in half vertically, then unfold.
4. Turn your paper over so the colored side is facing upward.
5. Fold the paper in half diagonally. It doesn’t matter which diagonal line you fold it on. After you’ve made a crease, unfold.
6. Fold diagonally in the opposite direction of the diagonal crease you just made. Then unfold so the colored side of the paper is facing upward.
7. When the paper is facing upward, you should be able to see that the paper doesn’t lay flat on the table because of the diagonal creases you just made. This is good. Gently press two sunken crease opposite of each other in towards the middle of the paper. The result is that the paper will take the shape shown above.
8. Push down on the edges and middle of the paper to make creases. This will make the base stronger and, generally, easier to use. Then you’re done! You’ve made a square base!
