Cast on question

I have a pattern for a felted purse that calls for cable cast on. Unfortunately, even after watching the video, I don’t get it. also unfortunately, I can’t post the pattern because it was a free download herehttp://www.houghtonavenue.com/felted-handbag-pattern.html
The question is, can I use long tail instead? will it hurt anything? This is going to be a birthday present so I’m pretty concerned. TIA

You could provide the link to the pattern… however. It should probably work out to use the LT caston instead.

fixed! sorry!

Since it’s going to be felted, I can’t see any reason to use a specific cast on; maybe it’s just one the designer likes…

Thanks so much!
