"Prolific Pyramids" - a finish

This may be called "Thousand Pyramids" but 1000 is too many this time.  All from my stash, except the backing.  I practiced "ruler work" on this one and was marginally pleased with what I did.  The end result is much better than I expected.  These triangles/pyramids are using the triangle from Tri-Recs, a little more graceful than the 60 degree equilateral triangle.  I called it "Prolific" because every time I turned around, another triangle was needed, and then those baby ones started showing up!

I was surprised with how easy this was and how many different ways the triangles could be set together, resulting in a myriad of variations.  I grouped 4 light and 4 dark triangles in each unit, and always had the darks on the same side each time.  I pressed seams open and again was pleased with the ease of sewing them, with reasonable care, as 2 sides were on bias. 

DH was holding this up and sun was shining thru.  It's all quilted and DONE.  

 Lots of straight lines, lots of practice with rulers!  I reverted back to free-form quilting in the side triangles. 

 Backing - isn't it delightful?  ... giraffes, with little blue baby giraffes.
