Note: I threw this together rather quickly so it is not as good as it could be XD
Anyways, I thought it may be helpful for cosplayers or Chobits fans out there who will randomly stumble upon this someday ^__^ If you have questions, feel free to ask, I'll help as best I can :D
1
Cut two shapes like this from your white foam. You may need to do a snip here and there to have it to your liking. This is just the general shape.
2
Now for the pink. Again, you will need two of these. It's basically the same as the white: it's a general shape and you may need to make a few adjustments.
3
Pretty self explanatory. You will need four white circles cut from your white foam.
4
Now, fold your white shape as shown
5
Fold the pink shape as well
6
Join the two shapes. Use your hot glue gun to attach them.
7
Now you use the hot glue gun to attach the white circle (do this on both sides)
8
Finally, glue the finished ears to your headband. Ta da! You now have Chobits ears ^___^
