## Feather Carving - Proportion and Expression Basics

Math is super helpful when making art, in all its forms.

Any time you want to make a drawing bigger or smaller, you can do it much easier if you use Math.

Proportions, percentage, and even expressions are important when making art.

Let's get started with some exercises.

Proportions, percentage, and even expressions are important when making art.

Let's get started with some exercises.

First, draw a sketch of a feather. This will be carved later, so don't make it too detailed -- just the right amount. This feather represents you. Will it show an animal? Will it be only designs? What are the designs you will be making?

Take your time to get this right!

Now, look at your drawing.

Your feather has a

No matter what it is, your object will have at least two measurements, a height and a length. If you drew something in 3D, you have a width, too!

Now, look at your drawing.

Your feather has a

**length**and a**height**.No matter what it is, your object will have at least two measurements, a height and a length. If you drew something in 3D, you have a width, too!

Now comes the tricky part. The wooden piece is actually a few centimetres longer than your feather. How can you make your drawing bigger, but still retain the proportions and the design?

I drew a feather and measured it. It is 16 centimetres long by 7 centimetres wide. My piece of wood is 40 centimetres long, so I know I can make it that long.

But how can I increase the 7 inches in the same proportion?

Easy.

16Y = 40

7Y = X

16 YX = 280Y --> divide both sides by Y

16X = 280

X = 280/16 = 17.5 cm

So,

Now, you do it!

Measure your feather and write down this length.

Measure the wood's length.

Figure out how much bigger you should make the width of your feather by using the method above.

Tip: Ask Mrs. J about the "ISTO" method -- it is a much faster way of figuring everything!

But only when you do the method above -- it is important to know where the core comes from, and then learn the shortcut.

**Let's look at the example below.**I drew a feather and measured it. It is 16 centimetres long by 7 centimetres wide. My piece of wood is 40 centimetres long, so I know I can make it that long.

But how can I increase the 7 inches in the same proportion?

Easy.

**Let's write what we know!**If you write what you know, you will be able to do this in the future just by looking at the data you have. No need for memorizing -- logic wins!**Old Length: 16cm**

New Length: 40cm

Old Width: 7

New Width: X

Proportion multiplier: Y (how much did the 16 have to grow, to turn into 40?)New Length: 40cm

Old Width: 7

New Width: X

Proportion multiplier: Y (how much did the 16 have to grow, to turn into 40?)

16Y = 40

7Y = X

16 YX = 280Y --> divide both sides by Y

16X = 280

X = 280/16 = 17.5 cm

So,

**the new width of the feather in this example is 17.5 centimetres.**Now, you do it!

Measure your feather and write down this length.

Draw the feather and the details inside onto your wooden piece.

Before you start carving, watch the video below.

Mrs. J also has carved flat things before and she can teach you some cool tricks to do.

Be careful with your digits! Wrap them before starting!!!

After you are done, you will be able to paint it with acrylics for a permanent finish!
