I use 2 things. My guild saves all lose threads, scraps anything material wise for pet beds so I keep a waste basket on the right side. I used one of the 3m self hooks to hang a small bag on the left side of my table for other papers like notes, candy wrappers! (yes) etc.
When I go away, I always bring my machine as I get bored easily. I bring a small basket that folds for all of my scraps mixed and just throw the out. To me this works great. I got the basket from the $1.00 store years ago.
