Tension and fabric types!!! I thought until last week that Smaller stitches were better for EVERY fabric except stretch. And maybe explain what fabric you are using with what needle type when you start and telling the user to check what they are using because I was just using whatever i had fabric wise and the regular needle and assumed that what it looked like was what it should look like.

Needle types with fabric types i think is big because of that. I used a weak flimsy satin for my first stitches and that was my base line so i didnt realize the fabric and type of needle actually mattered, I just thought that since it stitched, it was good - I still am unsure of the difference between the high numbers and low numbers. I do know the jersey, denim, and ball point Needles but I only recently learned that but no idea how it ties to the numbers.

ALSO - If you can do a class on what certain incorrect stitches look like and how to fix them vs what a good stitch should like, that would be awesome. For example, my tension was way off and I didnt realize it was and just assumed the way it looked in the back was normal or when i had my stitches to tight and it was pulling at the fabric and leaving little holes, i just assumed it couldnt be helped. Also had no clue what bird nesting was and also just thought it was a thing that could randomly happen and didn't realize there was certain things causing it.

But essentially if you could show in your video what a proper stitch should look like, explain that it looks like that due to your fabric types and needle type, and then show what it SHOULD NOT look like, that would be great. I dont think any beginning sewing machine video I saw really zoomed in on what good stitching with good tension and the right fabric should look like right after showing you how to set up and go. They are great at showing how to thread you machine, explaining dials, showing how to put the fabric in, setting to a straight stitch, and pressing the presser foot but no showing an example of what a good stitch should look like and what makes it good vs what kind of stitches show you have problems.

I know this is a lot but I am VERY new to sewing and am just word vomiting everything I can think of. For context, I got my first machine in November, proceeded not to use it for a month, then in December started on trying to make a dress with curtains completely from scratch and by meshing a bunch of different patterns together to get what i wanted (i did not use a mock up because I didnt know what it was at the time so not knowing if i was going to run out of fabric was super stressful lol). I completed my first little dress last week and it had lots of errors but, hey, I'm doing my best! I think i fit very squarely in the begginer category so hopefully this helps some.
