No foundation crochet is awesome. I just used it to start a scarf and it really does make a nice tension free start!
The Puff stitch flower
is really simple once you make one. I'm making a bunch of the blue ones and might end up with a blanket... or a scarf. Not sure yet! The purple one uses the puff stitch and will be a scarf.
The Star stitch makes a very light, soft scarf and I'm working on a blanket using the same stitch.
I feel like it's been forever since I learned a new stitch so learning all these has been fun.
