I was a little intimidated by this block because I had a fear of set in corners but it was really easy. Sometimes fears are just unfounded.
For some or other reason I forgot to take photos of some steps again, but hopefully it won't affect the little tutorial.
Trace or print the block diagram onto paper of your choice (to be used as a pattern for cutting fabric). I didn't take a photo of this, so please imagine the block below as the traced diagram. :-)
Cut out one "Section A" piece and one "Section B" piece from the printed/traced pattern.
Pin the "A" pattern to your background fabric and cut out, leaving a 1/4" seam allowance all the way around. The accuracy of this seam allowance is VERY important so if you don't have the CD, which will print seam allowances, I recommend actually drawing the seam allowance on the fabric with a pencil or disappearing marker before cutting out the piece.
Repeat until you have four "A" pieces of fabric.
I cut out two shapes at a time by pinning the pattern onto a double layer of fabric. I found trying to do more than that resulted in inaccurate pieces.
Using your main fabric and your "B" pattern, cut out four "B" pieces as above. Remember the 1/4" seam allowance.
Using a 1/4" seam allowance, sew the "B" pieces together in pairs as follows. Press.
Sew the pairs together along the long edge to get the "star" shape. Press.
Now for the set in corner.
Using a disappearing marker, make a mark 1/4" in from the edge on your "A" pieces where shown in the photo. Clip the seam allowance to the mark but not into the piece.
Make a mark 1/4" in from the edge of each inside corner on your "star" as shown in the photo.
Place an "A" piece on top of the "star" right sides together, lining up the fabric edges and the marks you made on the fabric. Stitch, starting at the mark, using a 1/4" seam.
Now line up the opposite edge of the "A" piece with edge of the star and sew the seam. I found that starting from the far end and sewing toward the center ensured more accuracy here. Because of the clip you made in the seam allowance of the "A" piece it should be easy to maneuver the fabric into place.
Press the seam allowance toward the background fabric and repeat on the other three sides of the star.
Trace the "melon" shapes from your diagram onto the dull side of freezer paper. Using a hot, dry iron, attach them to the right side of your main fabric and cut out, leaving an 1/8" to 1/4" seam allowance all the way around.
Baste into place on the block.
Using the needle turn applique method described before, applique them onto the block.
