I had given instructions a few weeks ago about the sashing, but if you haven't cut it yet, you will need:
36 squares 2 1/2" from the fabric that matches the setting squares
60 rectangles 2 1/2" x 12 1/2" from the background fabric
The outside borders are cut 6 1/2" wide, also from the background fabric.
If you are making the quilt according to the original pattern, you will need the sashing added to the quilt like this:
There are sashing pieces between each block and then sashing posts at each corner, even around the perimeter of the quilt. When that is complete, add the outside border.
A few ideas for you if you choose to deviate from the original quilt....
You could layout all the blocks without the sashing, you would just end up with a smaller quilt.
Katherine added a smaller inner border that matches the setting blocks. You can see it here.
John is doing all 25 blocks from the previous and this quilt along into one quilt top. You can see his progress here.
Once your quilt top is complete, you will need to baste, quilt, and bind the quilt.
A big THANK YOU to all of you who participated in the quilt along this time around. It's been great to see your blocks come together. I look forward to seeing the quilts come together and become finished objects.
There is a flickr group here, if you would like to check it out.
