I think, to make sure the pattern is correct, to write and edit while you are making a test sample. Typos, abbreviations, spelling and grammar can be corrected upon completion of the test sample. There are way too many patterns out there that are written down before or after and leave out important things. There are people who will glady test knit for a free pattern and this is a super way to assure correctness. It is timely and you may get discouraged and it will slow down the finished object but in the long run, you will feel confident that it’s a good pattern and free of error.
Another thing, we all do things in various forms to obtain the same end result. Remember that not everyone has your degree of understanding and make general notes for explanations. Sometimes wording gets confusing but if you’ll put yourself in someone elses shoes and read what you’ve written, you’ll be able to explain so anyone can understand. It’s not uncommon to make reference to videos or books but remember, if you’re going to sell or give to others, these references must have permission. Permission for references is usually easily obtained by simply sending an email to the source. Save these for your protection and I applaud you for wanting to write your patterns!!!
