blocks on point
 

When adding a border onto blocks set on point, is it better to have the border or the bias edge on the bottom while stitching?

It's better to have the bias on the bottom. And be sure to really starch the bias parts (but you probably already know that!)

Here's a link to a chart so you can cut those setting triangles with the edge on the straight of grain.
