This first picture is Herringbone Stitch, both flat and tubular. It's an interesting stitch and I haven't decided if I like it or not. I do want to try it using Miyuki Delicas to see if I like the way it lays or not, as compared to the round seed beads. I used a couple of YouTube videos to learn how to do this stitch. Two videos came from Beadaholique and teach Tubular Herringbone as well as Flat Herringbone Stitch and another couple of videos from Jill Wiseman.
This picture is of a chain (it ended up being a necklace) done in Chenille Stitch. I love this stitch and I'm sure I will be making plenty of necklaces in the future. This video from Potomac Bead Company helped a lot.
And these fun things started with the hollow square and triangle via Sara Spoltore's videos.I need to play with these some more and finish experimenting (see that spiral thing next to the tubes of beads?) The Peyote Triangles were also completed using Sara Spoltore's videos.
