For this outfit, I used two packets of fat quarters (6 different fabrics in each) from JJ Handworks. I cut 8 of the fat quarters first into strips (5-½ " x 18"), sewed them together alternating prints.
I then cut the yellow striped fat quarter fabric into 1/2" wide strips that I ran through my 1/4" bias tape maker (making a 1/4" turned trim). This I sewed down the center of the printed strips. Then I sewed alternating rows of the printed fabrics. Press well, and cut out your pattern!
The collar and placket is made from the last 2 fat quarters, with a "tip" of yellow stripe on collar points. The perfect "Jelly Beans" buttons are also from JJ Handworks.
