Hello everyone, here I am again.
@alle
Thank you so much for your helpful tips and comments. What I’m taking away from them for myself:
Note to Ina:
1. You can skip prewashing jersey or stretchy fabrics (especially for children’s clothing).
2. Always place the pattern on the fabric fold (so the fabric is folded over) and use one pattern piece to cut out 2 fabric pieces.

I think there are also patterns where the center seam is omitted. I can imagine that well too; after all, you save two seams. That would of course be easier to make in terms of the pattern. But all the little pants I looked at have a seam in the middle. I’ll definitely try one sometime where there’s basically no seam in the front and back, only at the sides.
And this is how it continues:
Step 4:
Now it’s time to sew. I did that yesterday, and it really frayed my nerves. So far I had only sewn non-stretch fabrics with the straight stitch on my sewing machine. That was easy. BUT jersey is stretchy and needs a different stitch, otherwise it pulls together and you get wavy edges.
This is NOT what it should look like. Here I sewed with a normal zigzag stitch (so, not a stretch stitch):
I experimented with a test piece of my jersey fabric to see which stitch and stitch width would give the best result. There are probably lots of stitch types, but for me the
"stretch stitch" won. Luckily my machine has such a stitch. Because of the interruptions in the zigzag, it allows for movement.
Question:
According to the internet, stitch no. 9 is a "pseudo-overlock stitch." It looks kind of similar to my no. 8. Does anyone know what it’s for? Can it also do "stretchy," even though it’s "pseudo"? The interruptions in the stitch are at the sides and not completely through the whole seam pattern. I haven’t tried it now because I was happy that no. 8 worked. I have a regular sewing machine, not an overlock.
Then I placed my 4 individual pant legs on top of each other and marked the "top" with a clip. So I wouldn’t get mixed up again.
Next comes pinning the first seam with pins.
Then the sewing actually began. I set the stretch stitch with stitch length 4 and stitch width 1.5. Well, that is certainly different on every sewing machine too. You have to test it on the particular fabric. For the next pair of pants, I would try setting smaller stitches here. The reason follows later. So here is my choice:
Now let’s start! Very obediently, I first
locked the seam: so I sewed a few stitches forward with the straight stitch, then back again. Then I set my
stretch stitch and off I went.
This is roughly what the seam looks like then.
You can see I didn’t get around the curve very well, and the fabrics shifted slightly too.
Because of the curve problems, I would set smaller stitches next time. I think then I’d get around it better, right?
Question:
Small stitches or large stitches, or what do you do to get around a curve better with a zigzag stitch? Does the seam mind if you stop in the middle and change the stitch? So can you adjust the size within one seam?
After I had also sewn the seam on the other leg, I tried to neatly cut off the excess fabric next to the seam. Jersey doesn’t fray, and you also don’t want to have more fabric at
the seams than necessary.
Question:
Do you also cut off the excess fabric beside the seam? And do you just do that with normal scissors? The fabric sometimes curls up, so you can hardly get hold of the fine little bit that needs cutting off. Or do you just leave it on, since it’s inside and no one will see it?
So, and because that worked well, I carried on right away. Then I sewed together the inner leg seam (I’m sure it’s actually called something else).
After that I placed the two pieces, now sewn together in the middle, on top of each other and closed the two outer sides with a seam. But here a problem came up at the end of the seam:
Although the fabric was exactly the same length, at the end of the seam about 1 cm of fabric was left over on the underside. Annoying. But I didn’t want to unpick the seam again. So I simply cut off the overhang. For jersey pants for babies that’s probably okay, but for bigger people one leg would now be longer than the other.
On the other side I had sewn from bottom to top, so I started with the pant edges lying exactly on top of each other. The tiny overhang at the top by the waistband probably won’t bother anyone if I cut it off there.
Note to Ina:
Whenever possible, always sew seams from bottom to top. But that requires spatial thinking and inwardly goes against me. But if it helps the result, so be it.
Question:
You pros, do you all always sew from a bottom edge upward? Or does it just not happen to you that at the end the two fabrics lying on top of each other are no longer the same length? That’s surely caused by the pull of the sewing machine or the feed or the fabric. But that’s too complicated for me. I don’t want to adjust anything on my machine; we don’t know each other well enough yet :-)
At that point I was already pretty happy and worn out from the tension. But for a first piece, the result is okay so far, right?
In the evening I then cut the cuffs. This is special cuff fabric, also stretchy. It is always folded over, and the folded side is what you see later at the edge.
Here too you have to pay very close attention. What is the grainline? The whole thing has to be stretchy in the right direction. And then it also gets folded together twice. So first, a dry run on the table. I changed my mind again about the color because the fabric I had originally planned to use was somehow too thick.
Question:
How do you distinguish between cuff fabrics? Do you simply collect lots of them over time and then choose the right one, or can you distinguish between "summer cuff fabric" and thicker "winter cuff fabric"? A beginner just buys "cuff fabric."

So, enough writing. Now it’s your turn: to read and comment. Thank you so much for your support with my first project. I now have to quickly make lunch, otherwise my husband will starve. And this afternoon I’ll keep working on the baby pants :-))
Best wishes from Ina
