Quilt: An Old Bow Tie Quilt

Long ago I worked on a charity blanket project.  This is one of the blankets I tried out as a sample.

This one was a quilt which was a 3-D quilt pattern.  Here is a pattern, though not the one I actually used.  I had a book on 3-D quilts which was fabulous but seems to be missing from my sewing library.  Here is a YouTube video showing how to make this block.
