I think I disagreed with every comment.
My little man has been designing his own sweaters since he was 10 years old. It doesn’t mean he can knit, his technical assistant does that, it doesn’t mean he can write a pattern (I think style craft provided the basic pattern which we modified with size changes, colour changes, and stitch pattern changes), he can’t make knitting needles, or spin yarn, or mine coal or drill oil. He didn’t need any of the technical expertise talked about in the video, but he did design his own sweaters.
People have been designing knitwear since long before patterns were written or printed and traditional knitters were designing and producing all sorts of items without necessarily knowing one method of short rows never mind multiple methods.
The ‘incorrect’ short row mentioned in the video, with the cut yarn, I don’t know the pattern but I do know you can pull the two ends of that cut yarn and zip up the ‘seam’ to make a tighter pick up. I’ve done it myself without even knowing it was in any pattern, it’s very effective and I prefer the result. If you leave the yarn attached it’s very hard to zip up without ruining the tension on row 1. I’m not an excellent knitter or expert in any knitting method but I do experiment and design.
I do see designing, modification, making choices, as an early stage in learning to knit, why not? As soon as a knitter chooses a different colour, cast on, or increase method they are making design choices, they are designing.
With regards to people selling patterns based on a fashionable image, good photography, active advertising, it’s really no different to the advertising and sale of any other product. Many well advertised items are substandard quality, buyer beware, it’s just part of life that we need to pay some attention to our purchases and that we will be fleeced from time to time.
AI patterns, hate them of course, but it’s just one of the recent snake oils we should avoid.
