Tutorials I've made are a bit scattered around, linked below.
(My very old website has a tutorials page, but the web design is outdated so it doesn't work well for mobile, pages are linked directly below which may or may not be very usable.) Note that most of my knitting patterns include photo tutorials in the patterns themselves!
