5. Build the ladder

• Locate the 5 matching ladder steps.
• Fold them all in half the long way along the dotted fold line.
• Apply a strip of Scor-Tape to one long edge between the tabs. If you look you will see additional score lines where the tabs will be folded back. Apply the Scor-Tape only between these lines.

• Use scissors to cut each of the slits open again. Cut right to the end but no further.
• This will gum up your scissors so clean them with Goo Gone once you are done.

• Take the first ladder step and with the folded edge first, slide it into the first slot on the side rail that you have applied adhesive to.
• Slide it right to the end of the slit and fold open the two tabs of the step and press to adhere.
• The edge of one tab will line up with the dotted fold line of the rail.

• Repeat with all 5 ladder steps, placing one in each slot. Be sure to always put the folded edge in first for visual consistency.

• Apply adhesive on the outside of the opened tabs right along the edge. I used a Tombow tape runner here. Do this to all 5 sets of tabs.

• The sides of the rail get folded around to form a rectangular hollow tube with the five steps hanging out from the side. 
• Fold it around, tuck it in and press to adhere.

• This is an important seam so look for a long skinny object to slide up the rail inside to press against and make a better seal. I used a letter opener.

• With the tabs on both rails at the same end, slide the end of the first ladder step into the tops slot on the second rail.
• Slide it all the way in, separate the tabs and adhere them in place.

• Continue down the side rail adhering all 5 steps in place on the second side rail.

• Apply adhesive to the outside of the tabs.

• Roll the second rail in and adhere together forming the second ladder side.
• Again slide a long tool up the rail to help with the pressing in place.

• The front half of the ladder is complete. Now make the back rails.

• Locate the two shorter side rails. They match but you need to work on them from opposite sides. One is the mirror image of the other. If you have paper that is the same color on both sides you will have to keep making sure you work on the mirror image.
• Place them as shown to help.

• Fold along all the dotted fold lines. Crease them well.

• Apply a strip of Scor-Tape the length the inside edge. Start just below the tab, and run it right along the edge.
• Add a second short strip along the outer edge of the angle tab. Leave the backing on this shorter strip.

• The side supports get attached to the ladder front, directly under the third step, on the inside. The front angle lines up exactly with the front of the ladder side rail. The top of the side support lines up with the bottom of the step.
• Press in place.

• Repeat with the second side support on the opposite side. Place them carefully. You want them to match each other.

• The back rails will be attached at both the top and to the side supports. They will be wobbly until the cross piece is added in a later step. Positioning is important. The top of the rails (not the tabs) meet at the top with the angle tab being placed over the outside of the front ladder side rail. The Side support will be adhered to the inside of the back side rail with its end lining up exactly with the back edge of the side rail.

• First, peel the backing off the the short Scor-Tape on the angle tab and gently place the tops together meeting in that corner. Don't press until......

• Position the side support and adhere that. It should line up with the edge of the back rail on the inside. Press that in place.
• Check the top angle tab again and then press that in place.

• Repeat on the second side taking care to match the angle of the first side.

You now have a wobbly topless ladder....

• Adhere the 2 X supports together. I used Aileen's Tacky spray. Byron would work here as well.
• You are just doubling up the layers here to create thicker card stock.

• Apply Scor-Tape to each of the four tabs leaving the backing on.

• Fold back all 4 tabs in the same direction.

• Measure up 1" on the inside of both back side rail and make a small mark.

• The X support will go between the back side rails.
• Peel the backing off the Scor-Tape on one tab and position it so it is above the 1" mark and aligned with the inside edge of the back side rail.

• Peel the backing from the second lower tab and glue it in place at the other 1" mark on the other back side rail work to adjust so the ladder stands square.

• Attach the upper tabs as well. The ladder will become more stable with this addition.

• Next - the ladder top gets added.

• Fold on all the dotted fold lines.

• On the inside of the folded box apply two 1" strips of Scor-Tape along the inside of the the two slits in the bottom of the box.
• Also apply one long strip to the long end tab. Leave the Backing on.

• On the outside of the box apply a mini glue dot to each of the 4 tiny corner tabs.
• Apply a strip of Scor-Tape to the outside of the two shorter side tabs.

• Slide the tabs on the top of the ladder up through the slots on the ladder top box. There are two on each ladder side. 
• Slide them up until the box bottom is resting down on the ladder legs.
• Peel off the backing tape on the Scor-Tape and fold the tabs in and on top of the tape adhering them in place.

• Bend up the 4 sides of the box, folding the corner tabs to the inside and adhering in place.

• Fold in the side tabs, peel the backing off, and fold the cover down and seal in place.

• Peel the backing tape off the last tab and fold down in front and adhere in place completing the ladder.

6. Add the Skeletons

• Take the skeletons and bend them into positions on the ladder. There are lots of variations in how to arrange them. Choose your own.
• Use glue dots on any hands or feet (or other parts that touch) to hold them in position on the ladders.

• Adhere the orange text on top of the black text shadow.
