A wrap tai (vikle tai in danish) is a mai tai like baby carrier with wider non-padded straps. I made one last week and the husband has just used it for a walk with Bess.
It is reversable with yellow dotted fabric on one side and penguins on the other. Oh and its really comfortable.
The next one I want to make is the pea pod hip carrier. Sascha Romeo has made a great tutorial on sewmamasew.
