Here you see the block as an old fashioned Strippy
Quilt, with haphazardly arranged blocks![ If you'd rather make
12" blocks the Large outer corner triangles are half square
triangles cut from two 6-7/8" squares-The Larger center squares
are each 4-3/4, and The Smaller center squares are each 2-5/8"!]
Happy Quilting Folks!
