Nicely done ... Another name for this is Apple Core!
I did a table runner in a course. It's a nice pattern and can be fun done scrappy too! and I learned a lot about patience in doing all the curves. Actually was quite enjoyable and relaxing!!
Though, I don't think I would want to do a whole quilt in it.
The binding is just the same as you would do for a regular quilt. Be sure to use binding on the bias. I made mine pretty narrow, and had no problems as the bias lets you have the give and take you need for the curves!
