A crochet representation of square numbers and triangular numbers, consisting of 225 circles.
Triangular numbers are what you get when you add conscecutive numbers. The circles with dark centres are
1 + 2 + 3 + 4 ……. +14 = 105
The circles without dark centres are
1 + 2 + 3 + 4 ……. +15 = 120
Add two consecutive triangular numbers and you get a square number.
105 + 120 = 225, which is the square of 15

TRIANGULAR NUMBER AFGHANS
225 squares are worked individually in crochet trebles (UK definition).
The backing is made in one piece and the circles are attached at the same time.
I love the idea of using circles to represent squares and triangles!
This is a double thickness afghan. Circles will not fit together without leaving gaps so they are all supported by a striped background. This means twice the work!
The version in the photo used DK yarns. Heavier yarns are not recommended although the design would still work.
The back has a simple pattern of stripes, which cannot be seen from the front.
It works well as a hanging room-divider as a different design is seen from each side.
