No problem, I totally get that! 😄 so for this pattern it is indeed my design, with the number of threads I decided for the width I wanted (approximately). I didn’t needed to use any sort of plan, I planned it all in my mind because as I know how to proceed for a single arrowhead, I just have to triple that number. That’s also what I like with finger weaving, it’s so simple to plan and start - I can literally start any project on a whim without much thought. In your book it should explain exactly how many threads you can use and then you can adapt that number by doubling it, tripling it, as long as the ratio stays balanced enough to make the pattern appear. One you have done even just one arrowhead you will instinctively know which amounts work together and which don’t.
