question about verbs

[soidisantfille.livejournal.com]

How do I form verbs ending in -ing? As in "I like to spend my free time reading, sewing, and drawing." I seem to remember it involves a -я ending, but I'm not sure.

Also, how do you say "for fun", as in "reading for fun (not for school)."

In the somewhat same theme as the previous post, how does one say "by verb-ing?" For example, "He helped his mother by washing the dishes every day"
