i can sweep through arpeggios pretty easily that involve multiple fingers on different strings. however when it comes to using one finger to press down on two (or more) strings, it completely throws me off. it just feels so unnatural to me and i have to adjust my wrist so much.

are there any videos or pictures or something on how to do this? it seems like such a simple thing but it makes my fret hand feel so awkward.

its not gonna feel natural at first but with lots of practice over time it will.
just start it slow and speed up keeping it clean
