Draw a straight line on a piece of paper. If it’s easier, put two dots on the paper and connect them. Not too bad, right? Now draw a circle. Freehand, no compass or tracing the bottom of a can. Does it look like a circle? Not as easy as a line.
I remember trying to lay out curves for the side of a hanging shelf I built a long time ago. I didn’t know too much about design, but I knew I wanted a gentle curve, not angles. I also didn’t have any drawing tools to help out, but I pushed through and came up with a design that wasn’t too bad. Straight lines and angles are simple, but sometimes you just need a curve.
Another curvy experience that was a challenge for me was creating rockers for a rocking chair. I knew it wouldn’t be easy, but I didn’t realize how a subtle change in the curve could make the chair a hazard rather than a comfort.
