I designed this block last year for National Pi Day. :) Because who doesn't know someone in their life that loves math or science. Now that math or science-y person can have a tote bag or zip pouch or anything else made with this quilt block designed just for them! :)

Cutting Instructions: From Dark Blue (or color of choice): (1) 2 1/2 x 7 1/2" (1) 2 1/2 x 2 1/2" (1) 2 3/8 x 2 3/8" (1) 2 x 6 1/2" (1) 2 x 6" (1) 2 x 2" (4) 1 7/8 x 1 7/8" (1) 1 1/2 x 3 1/2" (1) 1 1/2 x 2 1/2" (1) 1 1/2 x 1 1/2" From Background: (1) 2 1/2 x 2 1/2" (1) 2 3/8 x 2 3/8" (1) 2 x 12 1/2" (1) 1 1/2 x 12 1/2" (2) 1 1/2 x 8" (2) 1 1/2 x 2 1/2" (1) 4 1/2 x 6" (1) 3 1/2 x 4 1/2" (1) 2 1/2 x 3" (1) 1 1/2 x 1 1/2" (4) 1 7/8 x 1 7/8"
Place a 2 1/2" square of background and Pi fabric right sides together. Stitch from corner to corner diagonally. Trim, flip and press open. You should have a 2 1/2" (unfinished; 2" finished) HST or Half Square Triangle. Set aside.
Place a 2 3/8" square of background and Pi fabric right sides together. Trace a line diagonally from corner to corner. Stitch a scant quarter inch seam on each side of traced line. There's a "scant quarter inch seam" tutorial on my blog. Cut apart on traced line. Press open your TWO 2" (unfinished; 1 1/2" finished) HSTs. Using the same method, but using 1 7/8" squares of background and Pi fabric, make TWO 1 1/2" (unfinished; 1" finished) HSTs. Repeat with each set of 1 7/8" squares, until you have 8 total 1 1/2" HSTs. (You will have one spare.)
Assemble as per the diagram. And enjoy your piece of Pi. :) Your block should be 12 1/2" unfinished (12" finished).
