This elephant reminds me of Dumbo the Flying Elephant with the ruffle around the neck. There is also an example of this rattle with a neck ruffle in blue or pink, which look adorable.
If this rattle/teether is for a baby, then you can better embroider the eyes instead of using safety eyes. Unlike the name suggests, safety eyes are only safe to use for a child above the age of 3.
You can find the free crochet pattern of the Elephant Rattle on the website of Samyelinin Örgüleri. The pattern is designed by orguler_dukkan.
