I am crocheting the Triangular Shawl by Doris Chan, page 91, in the latest IK magazine CROCHET. There is an error on Row 1. The pattern repeat enclosed in brackets [...] that needs to be repeated 15 times is missing one step. After the last "ch 3", you must include "skip next 2 sc" or your work will end up crooked. For an advanced crocheter, it only makes sense to do it but to a beginner who is following the pattern word for word, that one ommision screws up the pattern.
I will try to email Interweave Press. My past attempts in emailing magazines have not been successful. Vogue Knitting has the worst customer service, in my opinion.
