Washing Babies Clothes

Going to start washing all my babys clothes to put together her hospital bag today I have the baby soap i'm just wondering, I bought this thing where you can put all your babies socks , mittens , and booties in so they won't get lost in the washer or dryer because supposably the washer and dryer " eat " them. Well i'm just wondering , if I put my babies onesises in there they wont get lost right ?
