Found this great tutorial @
playcrafts and want to show it to all of you.
Broken Herringbone Block
This makes a 12.5″ x 12.5″ unfinished block. All seams are 1/4″ and
while I press my seams open, you’re welcome to press them however you
see fit.
Note: I am left-handed, so please forgive the
left-handed ruler placement in the photos. I trim on the left instead
of the right. Also, if you figure out better ways to do things, please
feel free to share! I’d love to hear them.
You will need: 6 – 2.5″ x 18″ strips of fabric 3 –
1″ x WoF strips of sashing For the block shown in the tutorial, Gillian
had asked for pinks, oranges, and chartreuse/lime green on an off-white.
I generally choose two fabrics for each color.
Pick your fabrics. Six feature fabrics and one neutral for the sashing.
Once your fabrics are chosen, you will need to cut one 2.5″ strip
from each of the feature fabrics. These strips should be at least 18″
long (short edge of a fat quarter). Some of mine are longer because I
needed to cut from the long edge of a fat quarter. This is fine, but
will end up with more scrap waste at the end. Cut three 1″ x WoF (width
of fabric) strips from your sashing fabric. If you are using a fat
quarter, use the long edge and cut six strips instead of three.
Cut one 2.5″ x 18″ strip from each of your feature fabrics, and cut three 1″ x WoF (44″) strips from your sashing fabric.
The strips will be used in pairs, so find pairings that you like. I
tried to do each combination of colors, so one set was pink and orange,
one set was pink and green, and the last set was orange and green.
Pair up the 2.5″ strips.
Sew each pair of strips with a strip of sashing in the middle. If you
are using mismatched lengths of strips, start by sewing the sashing to
the shorter strip, so that you use less of your sashing material.
Sew each pair of strips with a strip of sashing between them.
Press and trim the ends.
Trim both ends of each pair of strips.
Now comes a design decision. Pick which fabric you want as the top
triangle of the block. If you’ve paired up the fabrics with each color
combination, the fabric color at the top will be the color that is shown
the least in the block. So if you want a pop of one color, that’s a
good color to choose. In this case, I knew I wanted the green to be the
pop of color, so I chose the green to be the top fabric. With your pop
color fabric at the top of the pair, sew a piece of sashing to the left
end, leaving ~1″ extra beyond the top print. This is just for trimming,
we’re not going to do anything fancy with it.
Add sashing to the left end of the pair of strips, leaving ~1″ at the top end.
Press and trim, lining the sashing up at the 45 degree angle mark on
your ruler (or mat) and cutting across the top. That should leave your
chosen fabric as a triangle which will be the top of your block.
Trim with the sashing at the 45 degree line on your ruler
Keep the trimmings from this, we will use it later.
Keep the trimmed strip pair for later.
Next, pick the next pair of strips and sew them to the sashing. For
my blocks, I generally matched colors because I liked the way that
looked. So for instance, the orange is the bottom color currently, so I
would choose the other pair of strips that included orange, and make
that my top color, as shown in the picture. This isn’t required, do what
looks good to you!
Sew the next pair of strips to the sashing
Press and trim the top of the block, lining up to the 45 degree angle mark on your ruler.
Line up to the 45 degree angle mark, and trim the block
Once again, keep the part you just trimmed off, we’ll be using it later.
Keep the part you just trimmed off.
Now trim the right side, which is where we’ll be adding sashing next.
To do this, line up the top of the block to the 45 degree mark, and
trim off the uneven bits from the pair of strips you just added.
Trim the right side of the block to prepare for more sashing.
Next, add a strip of sashing to the part you just trimmed. Leave ~1″ extra sashing at the top of the block for trimming.
Add sashing to the right side which you just trimmed.
Next, sew your last pair of strips to the sashing you just added.
Once again, I matched colors. Pink is currently the bottom color, so
when I sewed the last pair of strips on, pink was on the top as shown
below.
Sew the last pair of strips to the sashing.
Trim the top of the block, using the 45 degree mark on your ruler. Once again, keep the section you trimmed off for later.
Trim the top of the block, and save the remnants or later use.
At this point, I like to start trimming the block down, just so I
know where things are. I trim to 13″ square and then trim down to 12.5″
at the very end so I can adjust for errors if necessary. It’s also
important that the triangle at the top is centered on the block so that
you don’t end up with tiny pieces of fabric at your corners. So to
center the block, I first line up the triangle at the 6.5″ mark on my
mat (again because I’m trimming to 13″ first), and make sure the top is
straight on the mat as well.
Line up the center of the triangle at 6.5″ on your mat.
Once the block is lined up, I trim the side of the block at the 13″ mark. You do not need to keep the part trimmed off.
Trim one side at 13″
Then I flip the block, and trim the other side at 13″. At this point
you can just line up the edges, the center will stay where it belongs.
You don’t need to keep this piece either.
Trim other side at 13″
Now that we’re trimmed up, it’s time to continue on. Add sashing to
the angle on the left side and the leftover trimmed section from the
first pair of strips you added. They should nicely line up because they
were trimmed at an angle.
Sew sashing and leftovers from the first pair of strips you used to left hand side.
Press and trim both sides.
Trim both sides of the section just added.
The block is now over 13″ tall, so trim the bottom so the block is 13″ tall.
Trim to 13″ tall
Only two sections left to add! Add sashing to the right side, and sew
the leftover trimmed section from the second set of strips added to the
sashing.
Add sashing and the leftovers from the second pair of strips to the right hand side.
Trim the right side and bottom of the block.
Trim the side and bottom of the block.
Next, add sashing and the leftover trimmed section from the third pair of strips to the lower left side of the block.
Add sashing and the last set of trimmed section to the lower left side of the block.
Trim the section just added.
Trim the corner.
Finally, trim the block down to 12.5″, and you’re done!
Trim to 12.5″ and done!
The reason I trim to 13″ first is because sometimes those bottom
corners do not cooperate nicely. This happened about half the time, but I
would just trim them off at the last step. Here’s a picture of what can
sometimes happen. If it does, don’t worry, just work to trim it off
when you trim down to 12.5″ at the end.
Oops!
And that’s it! Here are a sample of the blocks in various colors. If
you are interested in doing the rainbow version, I used red/orange,
yellow/green, blue/violet as the pairs of strips.
