Study pages 10, 11, 16, and especially page 18 in Sizzling Quilts from aSimple Block. For a super-simple block like Woodpile to work nicely, it's extra important to have the right fabrics. Follow this checklist (page 6 in "Answers and Extras"):
Dark fabrics
Here's what you need for two safe, pleasant color schemes that go nicely together.
Rules for Light fabrics aren't as strict. I often use
white as Light A, then a small subtle print for Light B, and a larger,
but still subtle, print for Light C. How many different Light fabrics do
you need? As many as you want. You can use...
ï Only one Light fabric throughout (which can be
boring).
ï The same set of three Light fabrics, in the same
positions, in all color schemes (which can give some neat effects where
the blocks meet).
ïA different set of Lights in each color scheme
(which is most interesting).
Page 7 gives a handy way to lay out fabric to work up a good color scheme (actually two color schemes). Choose only the dark fabrics to start; the light fabrics will be easy to work in later. Spread out eight fabrics, staggering the ends (1" if using the smaller size mask on this web page, 1-1/4" if you use the size in the booklet). Pay attention to which direction stripes and designs go.
Place a mask over the arrangement so you see what the
fabric will look like in the finished block. Page 8 gives the Mask
for choosing fabrics for blocks with four steps. Make your own mask
for three, five, or six steps.
