Although it is true that the holes do appear rather random, it was exactly
what I needed. Now to get a new rolling pin. Mine is circa late 1970's and
a heavy marble. It's just a tad heavy to work with and apparently I didn't
do really good quality control in the rolling. A few of the crackers were a
tad too thick and those did puff up a bit. I also overcrowded the cookie
sheet. I used a small one. Next time I will either use a bigger one or
split them between two sheets. Easily solved though. I just had to put
those back in the oven for a few additional minutes to get them crisp.

What are marble pins good for anyway? I ordered one similar to what my MIL
had. But it might be too long. 20" and French style. Wooden. No handles
and slightly pointier on the ends. Methinks I should get a shorter one as
well.
