Whenever you draft, design,
calculate, or figure out anything
in patchwork, you never include
seam allowance until you’re ready
for fabric.
Please read through this entire sec-
tion before you start. You will not
actually use paper, pencil, and ruler
until Step 6.
- Get out all tools, rulers, and
graph paper (page 9). - Choose a pattern or block
design. We will draft a Sawtooth
Star.

and underlying grid formation.

Let’s Start Drafting
Once you are able to recognize the underlying grid formation of patchwork blocks, its time to test the waters. I
invite you to assemble your graph paper, rulers, pencil, and eraser and join me as I go through the sequential steps
of drafting a grid-based block. Reading the text and looking at the illustrations and photos, although important,
will not give you necessary hands-on experience. Doing is the key to learning, knowing, and understanding.
- Decide the size of the block.
Although quilt blocks can be drafted
in any size you desire (page 17), it
is easiest to choose a size that is
equally divisible by the basic grid.
For example, the Sawtooth Star
is drafted on a 4 × 4 grid, so it is
easily drafted in any size square that
is obviously equally divisible by 4
(4 ̋, 6 ̋, 8 ̋, 12 ̋). We will draft a 6 ̋
Sawtooth Star.

Don’t forget about less obvious
block sizes. For example a 5 ̋
block ÷ 4 = 11/4 ̋ grid. A 51/2 ̋ block
÷ 4 = 1.375, or 13/8 ̋, grid (see
Decimal Equivalent Chart, page
68).
- Determine the grid dimension
(the size of each individual grid) by
dividing the block size by its number
of equal divisions. For our example,
6 ̋ block ÷ 4 equal divisions = 11/2 ̋
grid dimension. I use a small hand-
held calculator for all my “figuring
out.” If your answer is not a whole
number, translate three decimal
places into fractions (see Decimal
Equivalent Chart, page 68) or tenths
to determine which graph paper to
use (10-to-the-inch or 8-to-the-inch).
Knowing the grid dimension not
only gives you the information you
need to draw the grid but also allows
you to measure your patchwork as
you sew (page 16). - Draw the chosen size of square
(6 ̋) on 8-to-the-inch graph paper
and lightly draw the grid formation
within the square. Here’s where,
together, we put pencil to paper and
walk through the door to creative
freedom!

You could easily change the
size of your block by changing
(or choosing) the grid dimen-
sion. For example, if your grid
dimension is 2 ̋, you would mul-
tiply 2 ̋ (grid dimension) by the
number of equal divisions (4),
which yields an 8 ̋ block. If the
grid is 11/4 ̋, you would have a 5 ̋
block; if the grid dimension is
3 ̋, you would have a 12 ̋ block.
Multiplying the grid dimension
by the number of equal divisions
determines the size of the block.
