These are otherwise known as WIPs. I have a few besides the Circle of Friends squares.
The last round of this thread mandala is very difficult. I have to wrap most of the stitches around a steel ring. I've started doing one point per day, which will guarantee that the thing is done in a few more weeks.
Here's another thread project - I have just recently managed to advance the three remaining squares to the second round. The finished piece will be 3 x 3 of the squares, which are called "Rustic Lace Square." Then I'll put a border of some kind.
I've decided to make ornaments. This one is finished.
These aren't finished - they need the top part and a hanging loop.
Finally here is the big WIP - another Granny Square Flower afghan for my mom. I have been making one square a day for 25 days (when this picture was taken - there's another one now). 11 more days to go, and then a border.
Last time I made this, I didn't make the poinsettia block (pictured) the way it said in the book. I put a squash blossom in the middle and made the leaves and petals be yellow squash and zucchini.
Finally, this isn't a WIP (it's finished), but it is part of the reason I have so many WIPs. I wanted to make a mandala and a bulb that changed color, and I did.
