Size:
Pattern is made for one size - 0-6 months, But it is
extremely easy to make them in any size you need.
I mentioned where you should add more rows for the
sole (I suggest to add 1 more row in each place to make it
one size bigger), for toe if you like you can work more
rows too, but you can also leave it as it is, and
instructions for heel will be the same for all sizes.
