In the original post, I wrote: "I've been researching the name of the block. Like it's often the case with blocks, it has several different names, but it looks like the most common is Ohio Star."
I was wrong. A good friend of mine - who's a gold mine of knowledge on patchwork and quilts - tells me, that this is NOT an Ohio Star block, but an Evening Star or Eight-pointed Star block.
The photo (and my quilt) is an Evening Star/four patch block that is: 4 by 4 squares (see right outline) while Ohio Star is a nine patch block: 3 by 3 squares (left outline) and the difference from the two is quite obvious. I stand corrected.
If you're interested in the subject, there are several online articles on block names and of course millions of pages with blocks. One of the better articles are written by Laurette Carroll, a quilt maker and collector from California: "Quilt Pattern Names" At the end of the article you'll find several references to books on block names and designs.
Now it's production time:
