There was a lot of trial and error involved in making my bear ears last week!
Here's the technique which worked best:
(I might also be using it for bunny ears at Easter)
|Here they are!|
Place the smaller pieces in position, with the straight edges aligned, and attach them
(either by sewing or glueing - either works fine)
|Turn through the open bottom part of the ear - see how the pleat makes it work?|
Now you can stitch your ears to whatever you please. I attached them to a hoodie, but an alice band could work just as well...
