It has been fun devising the colour bands for my Modern Throw, but after a while I found that I was repeating myself. So I looked for a way to get a true random sequence. I had decided on an even number of rows for each band, and it seems that 6 was the maximum, so I was looking for a sequence of 2, 4 and 6. The easiest way would be to throw a dice where 1 and 2 = 2, 3 and 4 = 4 and 5 and 6 = 6. But no dice was to hand, so I had to find another way.
The obvious solution would be to use the random function in Excel. With a little bit of manipulation I could get it to produce the random sequence I wanted. But to do that I would have to turn the computer on - not something I want to do in the middle of knitting.
Then I remembered my scientific calculator. It has a random function that returns a three digit decimal number. Perfect - easy to keep by my knitting and it gives an immediate result. I pick out the 2, 4 and 6es, ignoring all other digits, and I keep on pressing the key until I have the number of numbers I want. For one block the total should equal the number of rows in the block. This is even more exciting knitting - not having control of what the block will look like.
I understand that there are websites that will produce random numbers, but why let somebody else do the fun bit? I love maths, nearly as much as knitting.
