Before we get started, you will need at least one suitcase. The number of suitcases depends on you and how long your trip is.
Helping Tip: Do NOT put anything in your suitcase because you will have to see if you have enough supplies for your travel and see if your supplies fit in the suitcase later. Just lay it on the floor
First, check the weather for information about the climate and temperature of the place you are going to and the exact time.
Since you know the weather, you can pick out the best clothes for your trip. Each week bring at least 5-7 pairs of clothes.
After, fold your your clothes neatly and lay them on the floor with the correct pairs. Remember, add socks to the clothes. Now we are done with the clothing parts.
Next, you don't want to walk barefoot so we have to pick out shoes that match your outfit and is comfortable to wear on your trip. Stores you could go to: REI, Target, Payless Shoe Store, etc...
Continued, put your shoes you chose in a shoe box or plastic bag so your shoes won't dirty other clothes and materials in your suitcase. Lay them on the floor.
Now you are done with the clothes and shoes part. They should look like this on the floor.
After, turn your focus to bathroom supplies. You should bring toothbrushes and toothpaste in ziplock bags. Also, pack any dental or medications that you'll need in a ziplock bag.
This step is really important. If you have any liquids, make sure that it is maximized to 30 millimeters or less. Check if the liquid bottle is closed tight. Pack the bottles in ziplock bags.
Now you could start putting your materials in your suitcase. Be organized!
Lastly, you could pack your backpack with airplane materials.
Now, you should have all your supplies ready to go!
