The Most Important Part of all: WHY you have No Straight Seams with HDC
So first, let’s take a look at the 4 basic crochet stitches. One of the first things to point out is that the half double crochet is a half stitch whereas the single, double and treble crochet stitch are all full stitches (that’s how I see it).
Because of that and the bulk that gets created when crocheting a
Why HDC Stitches don’t line up in Rounds
So, here you can see it a bit more clear that the hdc stitches are made in the same shifted over when crocheting “on top” of a stitch from the previous rounds. That creates a shift and you won’t see a straight seam with hdc.
However, to use double crochet as an example, you can clearly see that, as a full stitch, the next stitch “on top” of a dc stitch from a previous round is not shifted over as much and actually gets straightened out when you keep crocheting. The V’s of the stitches (horizontal lines) line up and are parallel from each other which isn’t the case for hdc.
Proof that HDC Stitches Shift In Rounds
Let’s look at the
Now, let’s do the same test for a double crochet. Do you see where the dc is above the hook? Now, do you see how the V’s of that stitch align parallel to the V’s below that stitch? That is why a full stitches create straighter seams than half double crochet stitches.
So, now that you fundamentally understand how the stitches
How to Crochet a Straight Seam with HDC in Rounds
The below picture show how a typical hdc seam looks like in rounds when you follow a pattern and it tells you to do a ch of 1 or 2 in the beginning of each round.

Now, let’s look how you can trick the system.
