Learn to pack your brushes well when you travel. Paint brushes cost quite a bit of money! The last thing you want is for them to get ruined while you travel. Packing them properly will make sure that the bristles will not fray or get horribly bent. Though this tutorial is more geared towards those who are packing brushes in their suitcase to fly, it also applies to those who may be traveling a distance by car to go plein air painting.
Grab a piece of cardboard
First off, you want to find yourself a piece of cardboard that will fit the size of all your brushes when you lay them out. I use a canvas brush holder to first put my brushes in as this makes it easier to keep them in place. However, if you do not have a brush holder you will be fine without one. Just place them next to each other one by one on top of your cardboard.
Get some seran wrap
Take seran wrap and wrap it around your brushes and cardboard a couple of times. Make sure that the wrap is securely all around your brushes. The wrapping will keep your bristles from getting tangled with anything else.
Second piece of cardboard
If you wish to do so you can take extra precaution and get yourself a second piece of cardboard the same size as the first and place it on top. Tape the two cardboard pieces together on both sides to keep them together.
Place your protected brushes in your suitcase. Make sure that they are laying flat and try not to place anything too heavy on them. That should keep them well and safe so they can be in good shape for you at your destination.
