One of my treasured possessions is a vintage crochet book. Unfortunately, many of the patterns call for yarn/thread that is no longer being made, at least not by what the book calls them.
A project I would really like to work on calls for "crochet cord" but no size is indicated (it's a set of potholders). The photo of the finished project doesn't help much in determining what a suitable substitute might be. My first impulse is to go with a standard size 10 cotton thread or Perl cotton. Any suggestions would greatly be appreciated.
Thanks in advance.
