I haven't kept them all or had a running count, but I would guess around 20 or 25? For me it took awhile to figure out how to tiller, the first 4 or 5 attempts all broke during tillering or shortly after before it kinda clicked for me and they started to survive. From there I made a few more and got better before I started to rush the process and they really aren't anything special. And then I slowed down and started challenging myself with different woods/designs and started making thing I was proud of again and improving.
