the possibilities are endless...pintrest of course.
i searched 'felt masks' because i knew i wanted felt as a material - it is so inexpensive and easy to work with. i found the fox right away - it was exactly what i was looking for! the bear i had to get a little more creative with, i found some links for etsy shops and combining a few looks of my favorites, i sketched out this guy - who kind of looks more like a ewok/koala/dog, but rowan was happy with it and everyone guessed she was a bear right away!
stella still wears her fox mask daily - she loves it! i can't wait to make them more to add to their dress-up collections. i have even been eyeing up this little diy, and even picked up some of the supplies the other day!
here is the pattern i used: fox mask, via http://feelincrafty.wordpress.com/tag/fox-mask-tutorial/
just a small tip, after having to throw away my first attempt. i sewed everything together before i traced and cut the eyes out - you don't have a ton of error room and it makes it hard navigating your stitches around the eye holes if you pre-cut them. also, you might want to play with the size - this mask was pretty small, and even stella had a hard time seeing out of the eye holes with her little bebe eyes.
