well here are several common ways to hide hands when you don't want to draw them.
-put arms awkwardly behind back
-go to the extreme with your poses
-distract them with feelings so people won't focus on the hands
-make your oc an amputee and you can draw him/her with no problem at all
-(not listed on the drawing below but)draw your character with giant paws
//this is a joke by the way don't kill me. (but I did the big paw thing like 500 times in the past tbh)
