Let's make the pattern, take a sheet of A4 (or for some of you a sheet of Letter size paper).

Fold the paper over to make a triangle...

Cut off the triangle and recycle the rest of the paper :O)

Fold the corners of the triangle to make a square...

Take the triangle and use the folds to define the bottom edges of a cone (hope that makes sense!)

Across the cone base, mark a line...

Cut off the ends of the triangle...

Unfold the cone and you have your ear pattern. Sorry if that seemed over complicated :O)

Cut out 2 copies of the pattern in the black fabric - MAKE SURE that you allow about 2 cm or about an 1 inch around the point end of the pattern, like in the picture.

Please note the way the paper pattern is sitting on the black that is the way you will position your pink fabric in step 11

Cut out 2 copies of the pattern in the pink fabric - the same size as the pattern

Place on of the pink pieces onto one of the black pieces line up the bottom of the triangle, then fold a simple hem by doing a double fold of the black fabric trapping the pink fabric. So I mean fold about 1 cm (half an inch) then fold it again by the same amount which will capture the pink fabric. Pin and sew the hem. DO NOT sew across the bottom of the triangle only the hems.

You'll need to snip off the top corner to get a neat fold at the top of the hem.

Do both the ears...

You should now have to triangle shaped pink and black pockets. To stiffen the ears and make them less floppy I inserted a triangle of funky foam/stiff fabric about half the size of the whole triangle. Push it all the way to the top of the ear.

Get your bits of boa/fur...

Fold each ear...

Trap a bit of the boa/fake fur in the fold...

Sew the line that I've marked in the picture, from the point of the fold to about a third of the way down, make sure you trap the fur/boa

Hopefully you can see the line that I sewed across the ear...

Now trim off the two flaps close to the sewn line...

(As an after thought I should really revise the pattern-but you can adjust the size of the ears in the last few steps!)

I used sticky back felt for this bit but you could use contact adhesive and black card or even duct tape...

Cut some trapezoids (sloppy squares) to stick to the bottom of the ear...

I really like sticky back felt it's easy to cut, sticks well and it's cheap!

Here are the ears with the felt bottoms...

Flip the ears over, so it's sitting on the felt bottom and sew across the marked line...

This last bit of sewing, helps keep the ears in shape and also creates a grove for the head band/Alice band.

Hot glue time! - check in a mirror where you want the ears to sit of the band - put the band on you head when you check for ear position, I guessed the first time and got it wrong :O(

The grove caused by the last bit of sewing makes a fantastic glue line...

Meow... all done...
