With all the struggles I have with my left hand for chords on my uke/guitar, I've come to realize that I'm not strumming correctly with my right hand, either. To be safe, I've been just strumming with the outer side of my thumb to make it easier for a percussive tap to make a Chunk noise (which is just a tap on the E string). So like, what's the proper (if any) hand position for a pick-less strum?
