I would also recommend measuring the thickness with a micrometer or
thickness gauge. As Lots of the balsa that I've seen that is marked as
1/32 measured around .040 in thickness. The difference can translate
into a pound of difference.

This is a useful thing to do with balsa that you order from places
like LoneStar. The thickness is more consistent but a recent order for
1/32, 1/20, 1/16 contained sheets of .027, .031, .035, .040, .043,
.045, .050, .053, .060, .065
