Here is a new shirt, The Sophie Tunic by SisBoom. Actually it is the second one I made, the first in size 18m-2 years would not fit over her head. So with a few alterations I made one that would. I highly recommend this pattern - really clear instructions would make it suitable for even a beginner sewer. (Just check the size of your child's head first).
*Yes I know not the best way to talk about your children, but I have been told our family is not quite normal (usually by my Mum).
