Beware, some maths is involved ;)

I have had enquiries on how to make the never-ending card, so I cobbled a kind of tutorial together.  To make it easy for everyone to understand – as there are people who use centimeters and some use inches – I’ll show you the pictures with dimensions.  I’ll add lengths in cm for clarification (when you type ‘convert cm to inches’ in Google, they should give you a very detailed conversion, just round off I would say ;) )

The things you need to get the basic never-ending card is a square card or twice a square piece of cardstock, a cutting knife, a ruler, some double-sided sticky tape and some patience.

Here’s the card with all the dimensions:

A=2B; B=2C+D

It looks complicated, but it isn't, really

Impressive, no? ;)
The maths goes like this:
A = B+B
B = C+D+C

Now for starters, you need to cut your card in half so you have 2 squares (or start with 2 pieces of square cardstock). The length of the sides of your square = A (in my example 12 cm). Cut each square in half lengthwise, so you have 4 rectangles, measuring A by B (my example 12 cm by 6 cm).

Each rectangle now needs 2 cuts (D) which will make for easy folding. Turn each piece sideways and measure half of the width off left and right , top and bottom.

A = 1/2 B + B + 1/2 B

So your length of your card is divided:

½ B (3cm) + B (6cm) + ½ B (3cm) = A (12 cm)

Now draw lines so your single piece of card is divided in three: 2 small rectangles each side and a square in the middle.
Those lines you need to measure off again.
C + D + C
where C for me was 1cm and D 4cm, those who measure in inches can make C about half an inch, just make sure the card won’t rip, as now you need to make an incision over the length of D. Just scoring won’t do, as we have to fold back and forth. C will act as a hinge.

Do this for all 4 pieces of card.

Take two of the prepared card pieces and lay them next to each other like shown , put a square of double sided sticky tape where the pink dots are.

bottom cards

Take the other two bits of card and place them like shown and stick them on the other two cards.

top cards

put on top so open ends cross

Believe it or not, your card is finished (bar the decorating ;) )

Let me show you with cats, how they fold then – front:

So, all in all, there’s only 8 cats, but you can fold it whichever way, so different cats come together – as you can see in one of the former posts

I hope the ‘algebra’ didn’t throw you – otherwise, just yell and I’ll see if I can explain differently :D
