Folks have a dread about learning design. They feel that it is somehow beyond them. They are not artists. They are not creative enough. They lack the weird curiosity to be a designer. Or the hair.
Nothing could be further from the truth. Think back to your dreams last night if you want weird.
Design is not an immediate skill, but like throwing a baseball you can do it even at first. Your throw may be ungainly or downright ugly or straight into the ground. But you can throw. So too can you design, however badly at first. But like baseball, how many throws did you have to make to first before you could zing it there? Hundreds, maybe thousands. The same is true with design, but make the practice fun and you will succeed.
If you want the thrill of designing your own work, then you learn to practice its vocabulary. Learn the things that make up a good design: form, pattern, details. Study great design, design that appeals to you, and then reverently steal from these good sources. For after all, that is what good design is: reverent theft.
We have been stealing from nature for centuries as this ancient wooden sculpture from China shows.
