Do not use photographs; the trees, people, and buildings will get in in the way. Do not use a drawing that includes more than 1 side of the Eiffel tower. You will make each side 4 times, then glue it together to make a 3D tower.

Photoshop, or a similar program, will be your best choice for enlarging the image because you can set the size to inches or centimeters.

If you are printing a large image, be aware that you may need to print it out on multiple pages. Tape or glue multiple pages together to create a single image. Make sure that the lines flow smoothly into one another. Do not overlap the lines or leave gaps between them.

If your drawing spans multiple pages, you will need to shift these pages down and re-tape them as you move from section to section.

You can use wax paper, parchment paper, or even freezer paper, as long as the drawing is dark enough. You must be able to see the lines clearly.

To curve balsa wood: soak it in hot water for 1 hour, then bend it to your desired shape. Hold it in place with tape or string until it dries before using it. [3] X Research source

Do not use thin cardboard that is only white on the outside and brown on the inside. Have several craft blades handy. You will need to change them out as they will dull quickly. Dull craft blades won’t make nice cuts.

If you are making a cardboard model, cut out the entire base shape first. This includes the top, bottom, and side edges, as well as the arch.

Do not overlap the crisscrossing pieces or you will get too much bulk. Cut and glue the bars separately. If you are making a cardboard model, start off with the larger spaces, then move on to the small ones between the crisscrosses. [8] X Research source If you are using hot glue, follow the same process: horizontal lines first, then the crisscrossing lines. You can overlap the crisscrossing lines, however.

Skip this step if you are making a cardboard model. It might be a good idea to switch to a new blade if the old one is no longer giving you clean cuts. This step should only take a couple of minutes for hot glue at the most.

If you made a cardboard model, simply pick the piece up and set it aside. Create another template on another piece or section of cardboard. If you made a hot glue model, peel the glue off with your fingernail. Cut or pull off any threads left by the hot glue.

Skip this step if you made the entire model on a single sheet of paper. This includes hot glue models.

When making the roof, create each of the 4 walls and 4 roof triangles separately.

Use hot glue or super glue for paper, wood, and pasta models. Tacky glue will work, but you’ll need to hold the pieces until they dry. Use hot glue for hot glue models. Work 1 side at a time, or the glue will set too fast.

Skip this step if your model is all 1 piece.

Use a fast-setting glue for this, such as super glue or hot glue. A thick glue, such as tacky glue will also work, but you will need to hold the piece until the glue dries.

If you made a tower out of hot glue, you can make a small, triangular mount using hot glue, then glue it to the top of your tower. [15] X Research source

If you made a hot glue model: draw a thin line of hot glue on a piece of plastic, parchment paper, or wax paper. Let it harden, then peel it off. Glue it to the top of your tower.
