Use the right and left arrow keys to change the pen design. (You have to press flag again to see your new pattern.) Comment your pattern number! (If you want a specific color click the "See Inside" button and you will see a sprite called "Color Swab" You can show that and I have a pick color block that you can use. Then you just have to switch the two "Set Pen Color To ___" blocks.)
I was just experimenting and I got this.
