I will be starting this bag next week. Since the bag has to be crocheted together at the bottom, I can’t decide which CO method to use. Which one would you use? 
I think I’d do a provisional cast on and then do a 3-needle bind off for the bottom.
Thank you, Ingrid. It seemed to me that crocheting the bottom together could be a problem. The bag is for my sister and she carries a ton of junk in her purse. (she doesn’t knit so the bag will be a purse)
