1. Divide the jelly roll into colors. Select two color ways you wish to use on your shirts. I chose to use the yellow and green colorways for this tutorial.
For the Girls Shirt, select 4 green and 4 yellow strips for the flaps and 1 strip for the tie.
For the Boys Shirt, select 3 strips.Girls Shirt
2. From the 8 strips you selected for the flaps on the girls shirt, cut them in half on the fold.
Turn the Strip right side out, press and topstitch 1/8" on all four sides, closing the 3" turn hole.
17. Cut the following sizes from your 3 strips.
cut 2 - 2 1/2" x 5"
cut 2 - 2 1/2" x 7"
cut 2 - 2 1/2" x 9"
Depending on the size of your shirt, you may need to smaller or taller. I just kept a 2" height distance between the three strips.
Then fold the strip in half and then unfold. Fold the two raw edges in towards the center fold line and press.
