Foam k9 Ears
Diagonal tip to tip 7.25"
top tip to bottom ridge 4.25"
Edge to edge horizontal 5"
Sold in a set of 2, these are made with a flexible foam. Easily mounted on heads with glue because they have a thick base, or you can cut holes and sew them down.
These provide a skeleton of sorts for ears; you can then cover them in fur or fleece depending on what the head is made out of. They can also be cut with scissors, if you needed them to be shaped a little differently.
Just keep in mind that foam -will- yellow with UV exposure over time, so these are best covered.
