When I saw this on Pinterest, I felt silly for not thinking of it myself.
Keep a dry erase marker in the laundry area to note clothes inside the washer that shouldn't be dried.
We have several articles of clothing that need to lay flat or hang to dry and this will make it so much easier to make sure that they don't end up in the dryer. Just jot a quick list on the washer lid with a dry erase marker as you sort laundry into the machine, then erase once you have pulled the item out. (I have the marker pictured and it has an eraser and magnet attached, so you can just leave it attached right there to the washer lid!)
P.S. Buzzfeed has plenty more tips to make doing laundry easier here.
