I wrote a ton in this post:
Albem Bag
before realizing I have a very basic question:
If a pattern just says "decrease x sts across", is this referring to a certain "basic" way of decreasing which I should know about? Or does this mean you can go about it any way you please - be creative

?!
NB the question is not just with regards to the Albem Bag pattern. I also wonder what to do if I ever come across such a description again! But if someone has another idea about decreasing in that particular pattern, I'm happy to hear it.
