1. Lay the quilt flat, and then fold it once at a point slightly less than one-third of the width.
2. Fold the other side slightly less than one-third of the way and tidy up the folds so that no wrinkles appear. Good flatness.
3. At one-fifth of the end of the quilt, pick up a ridge five centimeters wide. If you stack the quilt thickly, the width should be extended. It should not exceed 10 centimeters at most, otherwise the quilt will become dregs. You need to dig hard at the ridges so that the three-dimensional effect of your quilt will be obvious.
4. Fold upward along the ridge.
5. Next, repeat step 3 on the other end of the quilt. At one-fifth of one end of the quilt, pick up a bulge five centimeters wide. If you stack the quilt thickly, the width should be extended. It should not exceed 10 centimeters at most, otherwise the quilt will become dregs.
6. Repeat step 4 and fold upward along the ridge.
7. Now a semi-finished product is formed, and the middle part still needs to be touched. Make a ridge in the middle part.
8. Fold upward along the ridge to form a basically completed quilt.
9. Cut out all eight corners of the quilt to form a stiff tofu block.
