Lil Threadz is a New Jersey based Etsy shop that specializes in creating eco-friendly shirts with adorably unique appliqués. The shop offers several fabric patterns that can be customized for your little one. The "age" shirts would be perfect for a birthday boy or girl. For those wanting more of an "everyday" shirt, check out the shop for equally cute shirts with cool designs ranging from hearts to rocket ships to ninjas. Lil Threadz has some of the sweetest shirts I've ever come across and it doesn't hurt that the shirts look so snuggly soft to boot!
