Here are the blocks on the design wall; I've already starting attaching the sashing.
The setting triangles that will fill in the sides and corners of the quilt are cut from squares that are larger than the finished quilt block. For the side setting triangles each square will yield four side setting triangles because the square is cut on the diagonal twice. The squares that are cut for the corner setting triangles will yield two corners.
There are two simple formulae for cutting setting triangles. The formula for side setting triangles is:
Finished size of block x 1.41, round up to the nearest 1/8" and add 1 1/4"
The formula for corner setting triangles is:
Finished size of block x 1.41 / 2 and add 1/8", then round up to the nearest 1/8"
This means I will need 14" squares for the side setting triangles and 9" squares for the corner triangles.
I used to struggle with this formula because it is based on decimal whereas quilt measurements are fractions. So what is an eighth of an inch when expressed as a decimal? The following list provides the measurements in 1/8"s and multiples thereof expressed as a decimal!
1/8" = 0.125
1/4" = 0.250
3/8" = 0.375
1/2" = 0.50
5/8" = 0.625
3/4" = 0.750
7/8" = 0.875
I keep a little chart pinned to my bulletin board. I include the 1/8" measurements along with a list of finished block sizes and the size of squares required for side & corner setting triangles.
I've finished the bag for my secret tote bag swap partner. Here are a few quick pictures of the finished bag.

I sure hope my partner likes her bag. She has left some comments on the Flickr page for this swap that would lead be to believe that she will be happy!
Until I post again, happy sewing!
