I always like to crochet, best not too large projects (because of the patience ;-))
The Shoe-torial therefore hits the mark: it is a tutorial on how to revamp shoes with crochet.
Great!
I think that it should work also by knitting, but anyway that’s not my cup of tea.
At the next opportunity I will check my shoes if they can be revamped that way ;-)
