I am making pinwheels by the Missouri Quilt Company method with charm pack sized pieces of fabric. My finished block is square. But, when I measure it, it is 5 1/2 inches one way and only 5 1/4 inches the other way. So how can it be square overall? What am I doing wrong?
I will be grateful for any assistance because I am creating my own pattern for a baby quilt for donation. Thanks. :)

How are you determining it's square? If it's 5 1/2" one way and 5 1/4" the other, than it is not square.
I would trim each pinwheel to 5 1/4" square, making sure that the center seams are at the 2 5/8" mark and that the diagonal seams are right at the corners.
Hope this helps!

I know what you mean, but when I measure on the diagonal for square, the measurements come out the same. When I use a square ruler - same thing. That just isn't right somwhow. I am starting and ending on the same numbers on the ruler. Thanks for the cutting down idea. :)

A - Square has four equal angles and four equal sides
.....The diagonals are the same length
B - Rectangle has four equal angles, two equal sides that are short & two equal sides that are long
.....The diagonals are the same length
C - Parallelogram has two angles that are smaller than 90deg & two that are bigger than 90 deg
.....Two equal sides that are short & two equal sides that are long
.....The diagonals are not the same length
The term square applied to A is a noun
The term square applied to B is an adjective. This "square" is used often in the building trade.
The term square cannot be applied to C
Your block as measured (5 1/2 inches one way and only 5 1/4 inches the other ) is a rectangle with equal diagonals.
