I love crochet, its a great pass time, do you know about it? 
I do know crochet. It's one of my favorite past times. My favorite type is the filet crochet. The grid-like lace looks awesome when finished. 
I usually crochet onto flat fabric boards to make wall decorations, What kind of crocheting is the most popular anyways? 
I would think that knitting is the most popular. You can make all kinds of garments. 
Yes my grandma actually knitted me a scarf one year, it was very thoughtful. What kind of stuff can you make with crochet, ive never tried making clothing.
You can make tons of things by crocheting from clothing to tapestry. Most knitting, a type of crochet, is done by machine now though
Yea I know a lot of people who love doing it the traditional way such as myself. That way you can do it slowly and not mess up. 
If you want to really challenge yourself by doing manually you should try hand knitting,where you use two long flat needles to crochet.
