My block of the day is Empire Star.
If you Google this block you will find is can be made entirely of half square triangles. Like this:
I didn't think this was a traditional block but I was wrong. BlockBase lists the source of this block as the Hearth and Home magazine. Barbara Brackman has a post about the quilt designer for Hearth and Home, Clara Stone.
Clara Stone's patterns were collected and published in 1906 in a booklet called Practical Needlework.
