New weavers don't get the connection between the various factors in the development of a cloth.
That is not a 'failing', just a lack of knowledge. It is only after they weave enough cloth, pay attention to the results, that they begin asking the questions they need to ask (if they follow the thread) and begin to understand how the answers in weaving are only ever *conditional*.
What do you want? What will it take to get you there? Which fibre? Spun in which way? Which weave structure. Even, what loom are you using?
The question of density is packed with conditions.
There are the 'ideals' and then there is reality, based on functionality.
I see people saying that true freedom is to ignore the 'rules', do what you want, free your creativity.
Which is all nice and all, if you don't care about the qualities you are building into your cloth. If you don't care, then, do as you will.
OTOH, if the apocalypse arrives, knowing the 'rules' and understanding the equation of time spent to get the cloth made and how well it serves becomes an issue, it might be a good idea to actually learn the 'rules'. Just so you have those in your weaver's toolbox.
I've been known to bend those rules in order to wind up with a particular quality of cloth. I'm not adverse to bending them until they 'break', just so I know that particular boundary, too.
So when I talk about 'ideals', I also hold space for bending the boundaries. So there are times when my twill isn't 45 degrees (after wet finishing), but maybe a bit more, maybe a bit less, sometimes very much not the 'ideal' at all. It depends.
When we shift the dial back and forth between this quality and that quality, we can fine tune our results. But knowing certain things - like combining stripes of plain weave *and* some other weave structure, like waffle weave, will produce certain results.
(receipts)
I have been known to do something like this *on purpose* - for an article.
Understanding the concept of dimensional loss (commonly referred to as 'shrinkage') should be understood. And if you achieve that dimensional loss, know that you are doing it willingly, not by accident. For example, the dimensional loss in waffle weave (or Brighton Honeycomb if you are in the UK) can be as much as 50%. Not a problem if you have woven samples and you know that going in, not just discovering that after you have woven your entire project and do not have enough cloth to do what you wanted to do.
So, do use your creativity. But maybe make a sample or three before committing to a large project?
