AI GeneratedThis tutorial demonstrates how to perform a decrease in treble crochet while working in rows. The instructor explains the process of combining two treble crochet stitches into one by omitting the final step of the first stitch and joining it with the second, allowing the crafter to shape their work into forms such as triangles or shawls.
Hi everyone, this is Deja
from CrochetEverAfter.com and right now I'm going to show you how to
decrease in treble crochet when you're working in rows.
I'm going to show you how to decrease in treble crochet
when working in rows.
I have a little short row of treble crochet already
so that we can work into it.
And when you start a row of treble you always need to chain 4,
that's to get the proper
This is the proper height
Now, I am going to take the next two stitches that I come
for your stitches.
to and turn them into one stitch by decreasing.
I don't work into this very first stitch.
Remember, if you need to find your stitches,
turn your work sideways and look for your letter Vs.
So this is my very first stitch.
I don't work into that because
my chain four counts as my first treble crochet.
So I leave that one alone and I go into the next two.
So to begin my decrease, what I need to do is yarn over twice,
like I would for any treble
crochet, and I insert my hook into the stitch,
and yarn over and pull up a loop, just like
normal.
Then, I am going to work up to the very last step of my treble crochet.
So that means I need to pull two sets of loops off of my hook.
So I yarn over and pull through the first two.
And then I'm going to yarn over and pull through the second two.
So that's two sets.
I work up to that very last step of my treble crochet
where I would yarn over and pull through those two loops.
I stop here and then I begin
my next treble crochet into my next stitch.
So I'm going to yarn over twice and insert my hook.
Yarn over and pull up a loop.
And then I'm going to do the two takeoffs again.
So I'm going to yarn over and pull through the first two,
and then yarn over and pull through the second two.
Now I have three loops on my hook,
and one belongs to this treble,
one belongs to this treble,
and one is the beginning loop.
So I'm going to finish this decrease
by yarning over and pulling through all three of those loops.
So now I have turned these two treble crochets
into one by just omitting that last step and
then combining it by putting those two together.
So I'm going to do regular treble crochet
and then we'll do another decrease.
So a regular one would be yarn over and pull through those first two,
yarn over, pull through
the next two, and then yarn over and pull through the last two.
That's a normal treble.
We just skip that last step to be able to decrease.
So we insert into the next stitch.
We're going to decrease these next two stitches.
Yarn over, pull up your loop.
Yarn over, pull through the first two loops.
And push your loops to your shaft if you want
nice even high stitches. Yarn over, pull through the next two.
Then I stop there and I begin my next treble. Yarn over twice.
Insert into the next stitch. Yarn over again and pull up that loop.
And then I'm going to work off two sets again,
yarn over, pull through the first two, yarn
over, pull through the next two,
and now I have those three stitches on my hook again.
So I'm going to yarn over
and finish off my decrease by pulling through all three stitches.
So now I've decreased this row by two stitches total
because I turned these two into one
and I turned these two into one.
So I took off two whole stitches.
Now if you do this consistently, what you can get is a triangle.
So this began as a row, and then as I went down,
I just decreased and decreased until I got to just four down here.
And you can see how these two are put together into one.
I could even do another decrease and make this even pointier.
But if you started with a huge amount of treble crochets,
and just kept decreasing every row,
or every other row if you want a wider triangle,
You can make a triangle shawl just out of this simple stitch
or you know you can do lots of different things.
You can make just triangles and sew them together.
Lots of different choices. But that is how you are going
to decrease in treble crochet when you're working in the row.
