Everybody works differently. I personally have always been a sketchy kinda gal... in many ways, but i do love the feel of the scribble when trying to take an idea out of my brain and into a 3D world. This is the sketch when i was figuring out this month's Blue Bird of Happiness project (Jan. 2021). You can see i don't always stick to the sketch - it's a just a 'getting started' tool, but if you don't already sketch to help bring form to your nebulous brain bubbles, maybe try it! if you don't like it, that's ok, but i bet you will.
