In the book How to Crochet by Pauline Turner in a pattern are two symbols which look like two crosses. What does it mean ?????
I get it it is suppose to mean go back to that same two symbols and repeat but I don't see the symbols earlier in the pattern.

It says "(two crosses symbols) rep from * twice more.
The two crosses symbols do NOT appear earlier in the pattern.

Is this a Britiush symbol?
