I'm a web developer by training who is branching into UI/UX design. One of the things my design work lacks compared to experienced designers is subtle use of texture, such as on these sites: http://www.trendkite.com, http://chartbeat.com
Do designers generally make these patterns from scratch, and if so, what is the best way to go about learning how to create them? The only freely available, subtle patterns I've seen that are as nice as this this are on subtlepatterns.com. I've had an equally difficult time finding tutorials on how to make nice patterns from scratch. Any resources you could point me to would be very helpful.
