Here is what the finish product was, minus the chocolate stains and the wrinkles. Please excuse those as I was finishing this onesie up literally 2 minutes before I walked out the door for work and didn't even think to snap a picture.
I went in search of a pink t-shirt, and would you believe I couldn't find one! How crazy is that, just a plain pink shirt and no store had them that didn't have ruffles or capped sleeves and all girly. My next stop was the resale store where I found this:
It was as close as I could get to what I was looking for. I used a seem ripper and took the ribbon off the sleeves, then cut the frilly stuff off the ends of the sleeves and hemmed them.
I used my cricut to make a stencil out of cardstock that said "boys wear pink", used some black paint to paint the words on the onesie (if I had planned on him ever wearing this shirt again I would have used fabric paint, however I knew this was a one time deal so Used acrylic).
I had leftover breast cancer fabric that had little pink ribbons on it, and since I accidentally made a black paint smudge in the upper left corner I decided to cut one of the ribbons out and cover my mess up.
I think everyone was suprised to see him going through the halls in bright pink but it was all for a good cause.
