I'm afraid that I'm guilty of using garbage bags to haul laundry to the laundry mat. At least the bags were brand new. I agree that using a hamper is the way to go.
Fortunately, we now have a new washer and dryer. Had them for about a year. The thing is, we bought them from Lowe's and once installed the dryer quit working the same day. The store took them back and exchanged the pair (Whirlpool) for Samsung. Worked great ever since.
I am giving some thought of building a clothesline in the spring for the backyard. Clothes would probably smell fresh and clean drying with the air and the sunshine. I never did mind going to the laundry mat but it's great to have your own washer and dryer.
Nothing like clothes that are fresh and clean.
