Do you like Crochet? Have you seen anyone make anything using it? 
I don't really know what it is, honestly!
Crochet is like knitting but crochet the stitches  are finished before proceeding to the next one. 
Oh that's interesting. I haven't known anyone that has been able to do that.
Crochet involves using a metal hook to interlock thread or yarn.
A hook? So is that different to knitting?
Yes. it is different in those regards I just told you. Knitting uses large needles that don't end in hooks. Buit the main thing is finishing a stitch.
