Cut two pieces of cardboard. Try to make them the same size! It took me a couple minutes to perfect mine too.
Take one cardboard and use your pen/pencil to mark your strips of cardboard. Use your ruler to measure 1 1/4 inches between each line.
By using your ruler connect your marks
You will end up with this
Make marks on your cardboard about 1 inch big and connect the lines with a ruler
*MOST IMPORTANT PART!!!* Do NOT cut all the way to the ends. Leave an inch of cardboard there
Weave through like this till you reach the end
Then on the next one you start at the bottom instead of the top. Keep if switching on and off with these.
This is how mine turned out❤️😍
