What is This?
 

I think it's fascinating, but I do not know the name so that I can find a pattern.

I don't know the name but it would be easy to make. Just three strips sewn together and then 1/2 squares on each end.

I know this block as "Cracker Quilt Block". Do you use Pinterest? If you do, do a search for Cracker Quilts. I just did and can't believe some of the quilts! I also did a google search and found a lot of examples including some for Pinterest.

I think it's an autograph style quilt block. There are many pic's on bing & google

Looks like you already had the Jinny Beyer link, with the same pic in both.

Another place for the pattern is "Cracker" block at quilterscache.com

If you follow this link and look to the right of the picture there is the information on making this block

I have seen it before. It would be good for two colors or print/floral and solid.

i will have to agree with zinnia ....

I like that. Seems like it would be easy to do, whatever size you want.
