Step 1: Needs
Khaki fabric for the hooves.
White fabric for the tail.
Black fabric for the tail hair.
A cow bell.
Poster board or foam core board.
A $1 cow nose from Party City.
Sharpie, black paint.
Step 2: Udders.
Cut out a piece that you think will be the right size...gland...for your pet. Then kinda free-hand it and sew it like I did. (Just make sure to sew right sides together, so you can turn it out, and have the seam on the inside.) I had no plan, I just made things up as a I went hahah. (I also stuffed a little cotton in there.) Once you have that done, take the seam of the fabric, cut pieces of that for the nipples, sew them on for best visibility. Then Add the elastic, make sure it will fit first.
Tip - my dog has random spots, so I put the udders on her, then I marked with a sharpie where she was black, so I could color that. The idea was good, but I don't know if I put it on backwards or what...didn't quite match up, lol.
Step 3: Nose.
I used a sharpie to color the elastic black, so it blends in with her head. :)
