make it happen! I've only done one true en plein air so far (see here and here ), but it was super fun and i highly recommend.

if you think this is something you'll do again, i recommend purchasing an easel designed for it. there are a ton available of all different types and price points, just search amazon for something like "en plein air easel".

I have this specific french box easel. Then then hand modified it a bit so that I can screw the canvas to the easel and so that there is no wood overlapping the canvas.

I like painting on canvases, so i'm not a lot of help deciding if you're looking at non canvases. There are "carry your wet canvas in a cardboard box" solutions on amazon you could look at, even if just to inform how you build your own.
