To great demand, here are the instructions to make my “poncho for two”.
Ispired by a “La Droguerie” model, this poncho allows you to cover/uncover with one move both mother and baby.
If you choose felted wool or pile your poncho for two will be ready in five minutes. All you need to do is cut, then sew on the buttons and make the buttonholes.
If you choose knitted material, like the one in the picture, you have to hem the seams. In that case you might need ten minutes.

The poncho for two is one size, if you’re quite tall and big, or petite, you might have to modify the measurements for your own personal needs.
