Assemble 9-patch. It will end up to be a 8 1/2" square.
Position QCR on left side of 9-patch, centering the dotted reference marks on top and bottom and left side of 9-patch at the 2 1/2" mark on ruler. Make your cut. Do this for all sides.
Take the 9" x 8 1/2" rectangle. Place the QCR on left side centering the dotted reference marks a 1/4" in from top and bottom and the left side of fabric sits at the 2 3/4" mark on ruler. Make your first cut.
Shift ruler to right. Again, center the dotted reference marks a 1/4" in from top and bottom. Now position ruler so the 4" by 2" intersection and 4" by 10" intersection sits on top of your previous cut curve. Sample above in red circles. Make your cut, repeat this 3 more times giving you 4 curves.
Position curve at 9-patch corner or 1/8" past corner and sew. Do this for opposite side.
Press seams from back, open.
Sew on other two curves. Before sewing, position curve a 1/4"-1/2" past 9-patch corner.
You can cut off extra fabric that is created after sewed as shown on on the back of my block.
Using your square up ruler. Square up 9-patch diamond to a 12" square, by cutting off the tips. I used the grid on my ruler to center my block as shown in red circles above.
It's okay after you've squared up that your piecing is not sewed to the ends (sample above). We will be squaring up again after the next step.
Take and stack your inside 5 1/2" hst fabric and place the QCR on top so the curve cut out sits from one corner to the other. Make your cut.
Position curved corner piece at corner - 1/8" past and sew. Repeat this for all corners.
Square up your block to 11 1/2" square, centering the best you can.
Sew on border fabric. You will end up with a 16 1/2" square.
Position QCR on the corner of your block so the corner sits under the 6" by 5" intersection. The 3" by 2" intersection and 9" by 2" intersection also needs to sit at edge's of block. (Samples above in red circles) Make your cut. Repeat this cut for all corners. *It's very important you are all lined up before making your cut!
Take and stack your outside 5 1/2" hst fabric and place the QCR on top so the curve cut out sits from one corner to the other. Make your cut.
Position outside curve 1/4"-1/2" past corner. Sew and repeat for all 4 corners.
Using your QCR, line up and cut off access corner fabric. Repeat this for all 4 corners.
You will end up with a 16 1/2" square.
