When doing alphabet blocks, I can't make the set of 26 come out even. No
matter how hard I try, I end up with one left or one blank space.

I even tried figuring out how to make the blocks with alternating blocks, no
luck.

I've already got the ABC blocks, so I can't combine two at the end. They're
redwork 8-inch blocks that I bought on ebay. Doing alternating blocks that
are red and white would be ideal, I think, but I can't get them to come out
even.

I'm curious how anyone else has done these, if they have. If not, how would
you make them come out even?
