As this was one of my most liked photos on instagram this august I figured I should share how I made these geometric beauties :)
These granny squares come out same size as original 7 round granny square.

It still needs to be properly written down .. but for those of you who understand crochet from half a word - I made half a granny square and then added rows on top of it. First row was 3 sc in each sp, second row in same colour was ch 3, skip 3 sts (to make 45 angle). Then dc in next 3 sts, ch 1, skip one st (repeat till there are 4 sts left till end). Skip 3 sts, make dc in corner for other 45 angle. And after thet you just make each granny row a bit shorter.

This one is simple - make four 4 row granny square halves and join them as you go.
after that make dc border (i made 2 dc's in each space and 1 in row joining points as I thought it looks neater this way)
