Sorry the picture's the wrong way:/

I found this picture by typing in Hufflepuff pottermore crest into google images.
You can either print it out or trace it(I traced it)

Trace another one of the badger and cut it out

Cut the badger out in black felt.

For the white patches I sewed on white linen and the line across its head is white thread.

The badger might take a long time... It took me ages to get it to look right

Trace and cut out the crest on a yellow piece of fabric.
Then I sort of singed the edges on the stove to make sure it won't fray

Cut out another white or black crest on another piece of felt.

Stick a safety pin into the back of the crest

Sew the badger onto the yellow piece

Sew the white crest onto the yellow part

Cut out another crest on black felt and snip out the inside.
Sew that onto the edge of the yellow bit...

Andddd DONE.
