Rectangle
Crocheting a granny rectangle can be quite tricky... and there are loads of variations for it (my first formula inspired by rectangle granny square i saw in Blair Stokers grannysquare sampler and a different approach for granny rectangle by Sue Rivers and probably many more I don't even know about) ... the latest revelation in this matter looks like this!

misshaped granny square!
Anyone who has ever tried to make a blanket out of mismatched size squares will know my pain of weird spots where nothing seems to fit...
There's always a possibility to make about a million small squares or use a rectangle here and there .. eventually get a straight line for a bigger square and after a while start that same cycle again.
sometimes it can be fun but most of the times it just gets on my nerves..
- why I am telling you all of this?
- I have found another way to fill the gaps! ;)
Let's welcome the misshaped granny square in to the BigBrightBlanket family!
The trick for making a misshaped granny square is to figure out the length of a starting chain and thickness or the rounds necessary.

I love math ! =]
I was inspired by the blairs grannysquaresampler. I had newer thought of rectangle granny square before and it made me think ... what is the amount of chains necessary to make a rectangle that fits the gap in a blanket?
I was obsessed for a while, I drew some rectangles starting from the outer edge and counted the chains in the beginning. And the more I drew the clearer it got. And that is when the formula was born!
btw, the rounds needed to make the rectangular granny square (R) can be caunted too ->
R=y-1
for example:
I need a square that is 4*9
so the x=9, y=4
that means z=9-4=5
B = 4*5-1 = 19
R = 4-1 = 3
this is the scheme for the middle of rectangle and the first round.
The dots are chains, but the small circle is loose chain (it will be needed to form the corners so it will have to hold 9 double crochet stitches!).
To understand the formula better I will show you step by step how I make one of the needed squares for BigBrightBlanket.

- x - longest edge (I am counting the holes or typical joining points of the typical granny square)
- y - shortest edge
- z - edge length difference z=x-y
- B - the chains needed for the beginning or middle
B=|4z-1|
