crocheting top to bottom instead of from side to side?

[Jean Marie]

Hi, someone on here said that someone was crocheting a blanket and was going to frog it cause it was too big but she suggested that they crochet from top to bottom instead of from side to side so she didn't have to take it out. What did you mean? As far as I know I crochet one row and turn and crochet the next row. That's crocheting side to side right? So how does one crochet from top to bottom instead of from side to side?

Example: If I crochet a dress and start at the top of the dress I'm still turning my crochet work after each row so wouldn't that be crocheting side to side and not top to bottom even though you're starting at the top of the dress?

What would it mean to crochet a blanket from top to bottom instead of from side to side?
