Here they are, all 86 half square triangles. Perhaps the next time you see them they will be on the quilt.
In order to make this quilt, I took all of the plaid fabrics out of my BAG OF FABRIC.
This is what is left.
Now to press these pieces and put them in a plastic box. There is a quilt in the Keepsake Quilt Catalog that is black and plaid nine patches set on point with alternating black squares. I have looked at that quilt for some time. I am seriously thinking about getting some black fabric and making one. If I do the plaid fabric will be all ready.
