Why Is The R Blue?

Judy and Lynda wanted to know why I didn't put the A in the Diagonals group of letters.  I bet they are also wondering why I put the R in the Blue group, and not the Center Block (Purple) or Diagonals (Green) group.

Remember, the groups are based on how the letters are MADE, or how they are constructed, not how they LOOK. 

When I make my R's, I don't start with a center block, and if I started with the diagonal strip, I'd never get the letter R the right size.

If you make an R this way, you can more successfully control it's finished size. Sure, you could put the R with the purples or the greens, but like the song says, "It's my party and I'll cry if I want to."
