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.

Types.
Types Flat knitting.
Flat knitting uses two straight needles to make generally two-dimensional (flat) pieces. Flat knitting is usually used to knit flat pieces like scarves, blankets, afghans, and the backs, fronts and arms of sweaters (pullovers).
In flat knitting, generally stockinette stitch, the hand-knitter knits from right-to-left on one side
Filet crochet
Filet crochet is a type of crocheted fabric. This type of crocheted lace is gridlike because it uses only two crochet stitches: the chain stitch and the double crochet stitch (U.S. terminology; known in some other countries as "chain stitch" and "treble"). Old filet patterns used a treble or triple stitch vertically but chained two between the vertical stitches. This was to prevent distortion of some patterns. Chain stitches use less yarn than double crochet stitches, which results in a visual difference in appearance
