My mother used to do Crochet.
Yes making things from loops of yarn or strands of other materials using a hook! Its fun but I feel it can be tedious. 
Yes I believe I tried learning to Crochet once, but I probably got bored after a couple days.
I always thought it was the same as knitting, but its not. When you corchet you finish the stich before doing the next one. When you knit your keeping several stitches unfinished at a time. 
Ineresting,  I believe it involved a different yarn too, and only a needle.  right?
Yes chrochet is done with a hook why knitting is done with one or two needles! They can be made of wood, plastic, or metal!
