The stroke tool in combination with pressure settings is very powerful and creates a wide array of interesting effects. Consequently, I suggest spending some time on it to get to know the ins and outs. It can save a lot of time and headaches later on. A simple and flexible solution often is best. Overcomplicating things leads to more work and problems. The stroke settings look complex but are one of those simple solutions for a wide range of design problems.
I hope you enjoyed the tutorial on Designing Octopus Tentacles in Affinity Designer. Play with it, add to it, rework it. Create your own Kraken, octopus, or fantastical monster of the deep. Most of all, have fun!
