What is a practical way to pack clothes that are still damp from a last-minute wash?
Quick answer
First, sort the laundry by how damp it is and how soon you need to leave. Give items that can dry in time a chance to do so before packing. If something must go while still damp, keep it apart from dry clothes in a separate, clean bag or compartment, pack it last, and unpack it as soon as you arrive. Avoid treating damp packing as a substitute for drying.
The question, the details, the next step.
A practical checklist
Separate dry clothes from items that are still damp.
Use the time remaining to dry items you can, then check them before packing.
Leave out damp items you do not need for the trip.
Keep necessary damp items in a separate clean bag or compartment.
Pack damp items last so they are easy to find and unpack.
Make a brief note of what is damp and where it is packed.
A few more useful answers
What if I do not have a spare bag?
Check whether you can use a separate compartment or leave the item out. If neither works, rearrange your luggage to create a distinct space rather than placing the damp item among dry clothes.
Should I wait until the clothes feel completely dry?
If you have time, use it to dry them further and check again before packing. If departure comes first, treat any remaining dampness as a reason to separate the item and unpack it promptly.
What should I do first after arriving?
Find and unpack the damp items promptly instead of leaving them bundled in the luggage. Your note about which items are damp and where you packed them can make that easier.
