I knit a boobtube some years ago which I never wore. It was a little too pretty/frilly/cutesy for me.
A friend recently had a baby daughter ... and the more I looked at the boobtube, the more I thought it would look great as a baby girl dress.
I only had to unravel about 3 inches of the boobtube to transform it into a baby dress. There was a bit of knitting and frogging to get the top right but it now looks pretty/frilly/cutesy - perfect for a baby girl!
The instructions are documented in Ravelry.
This one's for baby Katelyn!
