If four can be called a parade of penguins. This is from Jane Eborall's pattern page. I saw the one that Sally of Tat's Heaven tatted for her challenge/giveaway. I loved it and this pattern is amazing. I wish I could tat a replica of Tsuru in black and white threads. This is tatted in Milford Mercer size 40.
If you noticed that the first small penguin has an enlarged head. Well, blame it on the person who scrolled to the adult head and happily tatted away until she realised her mistake. So the lower photo has the correct sideways baby penguin in the correct head size.
