Sunflower No picture No picture No picture No picture No picture

This is my latest chipcarving project. For a number of years, I have been trying to find a pattern to make a sunflower, particularly the seed pattern. The problem is trying to create the spirals in the seedhead. As it is, the number of spirals found in a sunflower are in the mathematical sequence 1,2,3,5,8,13,21,34,55,... where the next number in the sequence is the sum of the prior two numbers. This sequence is called the golden ratio, and is found quite often in nature. This pattern has 21 spirals going clockwise and 34 going counterclockwise. I finally found something that sort of worked, so here it is. The plate is a 14” basswood plate stained with a light maple stain, and finished with 3 coats of spray polyurethane.

Keep it up.

What a fantastic piece of work. I’ve done some chip carving myself, but nowhere near this quality. But I do know what a high skill level you possess to turn out such work. I also like that you are a stickler for the details, which adds even more value to the piece.

Really cool, but that sequence of numbers is actually the Fibonacci sequence, it does create something really close to a golden rectangle but it’s a bit different

This article discusses the relationship

Very cool carving :)
