How much yarn do I need for a toddler hat and scarf?

I’m going to be at WalMart and possibly Hobby Lobby today, and I thought I’d check out the yarn selection for the hat and scarf I’d like to make my son (when I’m done with my dishcloth, of course).

Does anyone know approximately how much yarn I would need, if I saw something I liked?

A lot of the patterns I’ve seen don’t really seem to have how much yarn they use. :?? Maybe that’s because it depends on the type of yarn?

If anyone could help me with an estimate I’d appreciate it! I’ll probably look at the worsted acrylic, maybe? Or some wool or chunky acrylic.

I’d appreciate any advice. :slight_smile: :slight_smile:

You can get a general idea from this chart.
