Easy Half Square Triangle Tutorial...

Good morning!...are you ready for
another tutorial?
In my tute yesterday I said I would show you how I know what size to rotary cut the half square triangles in the blocks instead of using templates.
First of all...you need to know that I cut squares...not triangles.


           Go check it out and then
               come back here...
I'll wait:)
Okay...now that you know why I cut squares...lets get down to business!
  
 All of the squares in the block finish
at 2" x 2".
That means that I cut all of them
2 1/2" x 2 1/2"
to allow for seam allowance..

And when I say all of them...I mean that I also cut a 2 1/2" square for
each triangle too...

Like this.

Then I stitch them from corner to corner...

At the same time...by clothesline stitching.



I cut them apart and give them a
quick press to set the stitches...

Then I trim off the excess and leave an approximate 1/4" seam allowance.


Like this:)
No stretching out of shape because of
cutting triangles out on the bias...
I sewed it across the bias BEFORE cutting.
I heart this method:)

I know what you're thinking...
"That's some wasted fabric, Miss Lori"!
But remember I have cut my squares
from a 2 1/2" strip.
If I had cut squares and cut them in
half for triangles...
or used templates...
I would also have wasted a little fabric too.
Being able to cut a strip across the
width of your fabric,
 saves fabric in the end...
by not having to chop into your
precious fabric piece with
all kinds of odd ball measurements.

Although...
sometimes I do save my cut off triangles.
I save them if I can cut at least
a 1 1/2" square or larger out of them...
 and then I do.
If they are smaller than that...
I throw them out:)

I save my squares that I have cut from the leftovers for small projects.
You would be suprised how much I use them!

As you can see from the above photo...the leftover triangles from this block are
too small for me to save:(

Anyhoo...
when I press my half square triangle open...
it measures exactly
2 1/2" x 2 1/2" square...
because that is what size I cut
both of the squares that I stitched
from point to point.
I just simply made 1 half square triangle
 out of 2 squares.
Easy peasy math...easy peasy cutting...
easy peasy sewing:)

I lay the HST back out on my
mini design board after pressing...

And make sure that all four HST are facing
the right way..because I will sew them however they are laid out...haha
Now that it's turned into a simple 9 patch...it's a cinch to 
sew it together!


And that's how I do it!...
Yellow = Annies Farm Stand
Blue = Caramel Town
Red = Sew Cherry

Now that you know how to figure out what size to cut your squares when making HST...you can draft alot more blocks for rotary cutting!

Next post I will show you
how to draft/rotary cut/sew
a block that has flying geese.
Have a quilty weekend my friends:)

Perfect!
Do you always add a 1/2" no matter the size of the half square triangle?
I'm no longer afraid to start my blocks, and can hardly wait to get started on TFW! Thank you!

Cynthia said...

Ditto to Nedra ♥ Cutting squares is my favorite way to make half square triangles too. I am a visual person, so your tutorial really helped me a lot. Thanks! I am so excited I may not be able to sleep with visions of rotary cut squares dancing in my head :)

What I have been doing lately is after I sew from corner to corner I will go back and sew 1/2 inch from the first sew line. Then cut them apart. Now I have the HST that I wanted and a smaller set for use in something else. Thank you for the tut it was great!

You are making me want to do this! I'm telling you it is so incredibly tempting I can't stand it!!
