Another BOM - Attic Windows

This Attic Window block -- times two -- is super easy and super fast -- except for some reason I find it hard to get the corner block exactly in place.  Doing a corner block, as can be seen here eliminates mitering at the corner.  It makes sense and is easy enough.  But I've made many attic window quilts and  have devised my own method of mitering that works well.  I won't try to explain which is why I used this sneaky little trick for the BOM for the Bayberry Quilter's Guild.
