My biggest issue was getting the right yarns. The white is a baby wool, the tail/mane is cotton (I was able to get a small pack of mini yarns so I didn't have to get 7 50g balls). The tricky bit was the horn/hooves. I tried a few different silver crochet threats but in the end I went with some cross stitch thread. It was a very tricky bit to do as its only3 sc around, but I managed to do it...twice. I also had to try a couple of different eyes but found these at David's Emporium.
Of course, once I had these 2 I had to make a rainbow turtle friend for them :) (tiny striped turtle)
