How do I bind these angles?
 

[ATTACH=CONFIG]585018[/ATTACH]This is a 33" table topper I'm making for a friend. How do I bind those points. I think I know how to do the outward points, but what do I do with the inward ones?

What about the "birthing method" instead of binding?

Birthing is a good idea, as is adding facings.
Marci Baker has good you tube videos on binding different angles:

Binding non 90 degree angles:

The outer angles are 90 deg so you should be able to do a normal corner on those. The inside ones will be tricky.

If you cut your binding on the bias you will be able to ease it round inside angle.

Use Bias binding. It's easier than it looks. You actually pull the quilt almost straight to sew through the inside angle.
I was really nervous when I had a quilt with 90 degree inside corners, but it turned out well following these two videos.

Many thanks to all of you. I knew I would find the answer here.

This table topper is reversible with multi blues on the reverse. It was a total experiment turning a pattern for a 58" tree skirt into a 33"reversible table topper. My geometry class from second year high school came in handy. Used up lots of scraps, but there are still piles to be used.

It's wonderful!

I am so glad that you mentioned what you learned in geometry. Most kids say, "when will I ever use this". My answer was "you never know".
