SETTING BLOCKS

When determining the measurement of a
setting block, add 1/2" to the finished block size. This

will allow for 1/4" seam allowances.

REDUCING AND
ENLARGING BLOCKS

Always double-check the measurements of the final image
after reducing or enlarging it.

Enlarging a block: 12" block (desired size) ÷
6" block (original size) x 100 = 200%
Reducing a block: 4" block (desired size) ÷
6" block (original size) x 100 = 66.6%

CONVERTING YARDS (FRACTIONS)
TO INCHES TO YARDS (DECIMALS)

1/8 yard = 41/2 inches = .125 yard
1/4 yard = 9 inches = .25 yard
1/3 yard = 12 inches = .333 yard
3/8 yard = 131/2 inches = .375 yard
1/2 yard = 18 inches = .50 yard
5/8 yard = 221/2 inches = .625 yard
2/3 yard = 24 inches = .666 yard
3/4 yard = 27 inches = .75 yard
7/8 yard = 311/2 inches = .875 yard
1 yard = 36 inches = 1.00 yard

Fat Eighth
9 x 22 inches = .25 x .575 yards

Fat Quarter
18 x 22 inches = .50 x .575 yards
