I don’t speak French and Google Translator isn’t very helpful when it comes to knitting patterns and terms, so I made this from the picture, measuring the actual size of the phone to know the needed dimensions. =)

Maybe something’s wrong with my gauge but this cozy fits the ordinary Samsung phone, you know, those with buttons =)
for Iphone my cozy wont fit ever, but that’s OK, for my mom’s phone it’s size is just perfect.
