I used 2 balls.

I watched one video where they put the stitches on from the left hand side and my stitches all looked like more than one thread and hard for me to tell what I was doing, but this video shows it casting on from the right, then just transferring the needle to the left hand, and they all looked like one thread and easy to understand. DON’T USE METAL NEEDLES! I had to keep starting over because my needle fell right out and I couldn’t recover my stitches. I switched to plastic and always use point protectors when you lay it down, or they will slide right off the needles, even plastic.

Adding this info much later: I THINK I did 15 stitches, I may have skipped every other loop, wish I had written this at the time (
