With right sides together, place the "A" piece (going vertically) on top of the "D" pieces (going horizontally, and draw a line from upper corner of the background piece to the bottom corner of the star tip piece. See the picture to get an accurate idea of what I'm talking about....Then stitch on the that line, cut 1/4" in from the line to trim the excess fabric, and press the seam open.
Next, we will sew on the left-side star tip. Once again, with right sides together, with the "A" piece going vertically and the finished unit going horizontally, draw a line from the top left corner of the background piece to the bottom right corner of the star tip piece. Sew on the line and cut off the corner 1/4" away from the seam. Finally, press the seam open to reduce the bulk. Make sure that when you press your piece you keep it rectangular...don't let it curve like a boomerang when you are pressing!!
It is now time to assemble the block. Grab a center four-patch unit, your star tip units, and four 2.5" x 2.5" background "E" squares. Lay our your pieces like below... Sew the two "E" pieces to the sides of each star tip unit, and two star tip units to the sides of the four-patch unit. Press the seams open to reduce the bulk...
Now, attach the top unit and bottom unit to the center, pressing the seams open.
You are finished with this part of the block...it should measure 10.5" x 10.5". ;-) Yeah!!
But what if yours isn't quite 10.5" square?? If it is a bit big, square it up to the correct size.
If it is a bit too small, square them up to the same size...like 10.25" x 10.25". This will mean that you will also have trim your sashing pieces down to 10.25" from 10.5", but no biggie!! Easy peasy!!
Ok, come back on August 13th for the next step--the sashings and the center quilt assembly!! See ya then....keep sewing!
