I throw my smaller pieces into lingerie bags. I pre-wash everything no matter the size. You can make your own lingerie bag. I've used old pillow cases and even old panty hose. You can get plus size panty hose at the dollar stores and/or knee highs. I just don't use anything until it's been pre-washed. I also wash in hot water to make sure it has shrunk as much as it's going to. I have old trimmings like bric brac that I wash in panty hose. Toss that into the dryer on low about 10 minutes or roll into a large bath towel and set aside for an hour or 2.
