Lacy granny square

I present to you the newest block in the town!
Lets welcome the Lacy granny square ;)

It is fun, simple and supercute if I may say so myself :)
And it will be a great addition to my BigBrightBlanket.

So here comes the scheme!
I was drawing the scheme thinking how lacy granny square would be made using just one color.

O, and I made up symbol for half double crochet because google hates me ... and the last row I draw black, because I use it only if I need to make the square bigger or end it like typical granny square.

So here are some color variations of this square I have already made :)

Hope you'll have fun with it too! ;)

p.s. I'll try to write soon about the diagonal color change of a granny square.. but the most attentive of you will probably see the key point for that in this scheme too ;)
