I put mouths on some. Some I leave without. I use a fine line marker for this. I try to mix it up a little.
For the noses I use orange paint. Again, I try to make it so no two are exactly alike. If you use a small brush, you can dot it where the nose begins and drag it in the direction you want to make it look like a long carrot.
I save all my scraps and this is the perfect use for them. Small thin strips are tied around the "neck" or joint of the pin. I display these in a large bowl or basket. Customers love to go thru the bowl, finding the right ones.
You can use these to decorate packages, hang on the tree, or even put on a piece of jute for a garland.
