This is motif #109 from a favorite book of mine:
This adorable block involves edc(extended double crochet) and a leaning tower stitch and a partial leaning tower stitch ~which I have never done before~ but! it gives the block a unique, stacked stitch that is really quite easy to do (and nope - I will not share the pattern...Seriously! get this book! It is a must-buy-for-your-crochet-shelf!)
I am just using scraps of yarn & a G hook.
And having learned from past granny square making...
....I am weaving the ends of all those color changes as I finish each block.
Because waiting until the end when you stacks & stacks of blocks ...
Um. Not a good thing.
