I sold the one Valentine onesie that I had listed, so I've put up a custom order listing now. The customer can choose whether they want a onesie (sizes 3 - 24 months) or a tee (sizes 6 months - 4T) and whether they want long or short sleeves. Colors can be changed, too, although so far the only examples of I have are of this same basic scheme.
I think these are just so cute and my own daughter LOVES the one I made for her - so I'm hoping to get lots of orders!
