Cherry blossom time! All we need to do is to tell the turtle that small branches are to be drawn in red. Something like:

if :distance < 10 [setc "red]

Trouble is, once the colour gets changed to red, it stays red.
So, just before the end of our vee procedure, we need to set the color back. I decided to use brown.

Exercise 30 Can you make your tree blossom? Check.

Another new word to add to the fun: setpensize. Check out "Turtle Words" below for an example.

Exercise 31 Change the pen size and draw your tree again. Repeat until almost bored.

Exercise 32 It would be exciting if the tree branch width depended on its length. It would be even more exciting if you could change your vee procedure to do just that without any help from me. Check.
