PJ Set for Nephews - With Initial

My brother and sister-in-law had twins back in May so I figured they needed a way to tell them apart 10 Christmases from now... felt appliqued initials! I just bought some white T-shirt onesies (regular T for the toddler), ironed some interfacing underneath, and stitched a felt cut-out on top. I will definitely be using this technique again!
