I used a blanket stitch this time for the appliques - took a lot more time but it shouldn't fray this time. The tees are Ottobre and the romper is Kwik Sew 3090 ( I think).
The only difference in the appliques is the size of the dirt being pushed. It gets bigger as the size gets bigger - hopefully the boys will be able to tell the difference when it is time to get dressed.
If you click on the title, you can see the original post I made about the applique.
