Hey everyone! This is the second part of my pop-up
book of opposites tutorial. I would sincerely recommend you read part 1 as it
is an important introduction to this tutorial series. If you missed it read it
here. In this post, I will discuss the method for the cover page.
It is difficult to add any 3-dimensional pop-up components on the cover directly since there is no central fold. In order to compensate I added some fun components using a pull strip and hub and pivot mechanism.
Part 1: “Opposites” Pull Strip
Here I have used half of a blue A4 size sheet of paper
as the base to the cover. I left about an inch on the left side of the sheet
and drew a line vertically of length 16.5 cm roughly leaving the same amount of
space on the top and bottom. Remember to mark this lightly as it will
eventually be erased. It is only for an estimate of where to draw out the
letters. Divide this line into 9 sections for the 9 letters of the word
“opposites”. Now trace out the letters and cut it out from this section using a
blade.
Next, we have to turn this sheet and we will work on
the back of this sheet. We need to make markings on each side of the letters
cut out. This marking is made at a distance of about 1 cm from the cut out
letters on each side. Basically, we need to draw rectangles to the height of
the letters from this mark. To the left side of the letters, the width of the
rectangle is 1 cm. I did the same thing on the right side as well, but this
turned out to be a mistake which I corrected later on. The width on the right
side needs to be about 2 cm, else when we pull the strip it comes out of the
loop and when we push the strip it won’t go back in.
If you have not guessed already, these rectangles
marked are for loops that have to be stuck. Now since the length of the strip
is long, the strips of paper for the loops need to be over double the size of
the strip. So, in this case we need to stick two strips of paper for each loop.
The width of the left-side loop is 1 cm and that of the right-side loop is 2
cm. The colours of the paper used for these loops do not really matter as they
would not be visible.
Apply glue to the rectangle drawn on the base sheet
and stick the lower side of the loops to this. Following this, place the white
strip inside the loops to and stick the ends of the loop. Make sure to apply
only a small amount of glue else any glue that leaks will end up sticking to
the strip.
From the left side loop, mark a spot 7.5 cm away. Then
vertically mark the midpoint of the length of the letters cut out. From this
midpoint mark about 2.25cm cm on each side to get a line of 4.5cm. Mark two
very small inwards tapering cuts as shown in the overview picture. Use a blade
with a mat under the paper strip to cut out this slit. The inward tapering cuts
are to ensure smooth movement.
The 2 steps above can be done in any order. As you see
in my pictures, I have gone a bit back and forth on each step.
Put the strip back through the loops and the slit, pull the strip so that the colourful section is visible through the letters. Now carefully turn the sheet back. Here we will add two small strips of paper each side of the strip right next to the loop. This works like a stopper so that the strip cannot be pulled any further. The length of the strip can be a little smaller. When I do the binding of the book, I actually cut the length a little. It just needs to jut out a little beyond the loops. Also, the length it is currently, I do not have any space at the edges of the blue sheet to glue it later on.
There you are, the pull strip is ready. I wrote “Pull me!!” at the corner of the pull strip to draw attention to it.
Part 2: Smiley face Hub and Pivot
Next, I take the smallest circle (4), which is of a radius of about 1.2cm. Slits are made on opposite sides of this circle as shown below. For reference if you see the outline picture, cut where the dark lines are and fold the dotted line. When these slits are folded they should just about fit through the hole in the bigger circle (stuck 2 + 3, let’s call this circle 5).
Lastly, I drew a nose for the face just to fill up the
empty space in the centre. There you have it your smiley face hub and pivot is
now ready.
Part 3: Background
Once I was stuck the two components on the base sheet,
I added some basic lettering with gel pens.
That completes the tutorial of the cover page. Hope
this helps. I will return soon with the next blog for the next page. If you have any questions, let me know in the comments below. I know this is not my typical video tutorial series. But somehow I felt written with outlines are more important to follow the procedure. The gifs may appear fast but they are technically not required. You can follow the written instructions with the outline pictures easily.
Until next time. Bye!
