Fons and Porter called this "Crossed Canoes." They did an episode on this pattern a few months ago. (Have it on the DVR) Awesome find. Have fun with them.

Somebody did a great job of hand-piecing. Lucky you!

I love the fact that they are hand sewn. I am happy for you.

They are fabulous!

Look at the link here to see how gorgeous those blocks can look without sashing as well.

crossed canoes is the pattern.

Awesome find

Very cool. I wonder who made them...and why they remained a UFO. Clearly she knew her stuff! (Note my gender bias!)

What about a narrow black sashing?

What a great find.
