Painting at my first Paint-Out
(I took too much stuff)
The airlines are charging extra for each suitcase and the limitations on weight are being watched with an eagle eye. But even more importantly, taking too much stuff just in case you need it will weight you down in many ways. You are the one responsible for carrying your suitcase and if you don't find it easy to handle along with your hand luggage/laptop/purse you may be in for an unpleasant surprise when you're asked to haul everything up 2 or 3 sets of stairs, on and off trains, from one terminal to another, or from your car to your second story motel room.
I took way too many small bags on our recent road trip... a small suitcase, my laptop, purse, camera case, and tote bag of art supplies, plus we had a couple of food bags. All that stuff created unnecessary misery for both of us even when we could back the car up to the motel door. I'll never do that again. If I can't get everything into one suitcase and one tote bag it isn't going. If I need something that I didn't pack I can buy it or get creative with what I have. And I've found that too many articles of clothing usually isn't the problem because I wear the same garments over and over ... it's all the rest of what I take, "just in case", especially art supplies.
In this month's Daniel Smith newsletter you'll find a useful list of painting supplies for travel.
Elizabeth St. Hilaire Nelson wrote several posts about packing her collage supplies in her RV, here, here, and here.
John Lovett posted his Traveling Art Material List here, here, and here.
There's a link in my sidebar to an article I once wrote about packing clothing for travel. This may help if choosing a travel wardrobe is an issue.
