I cut piece of biggish linen and tape it to heavy cardboard to take to open studio. The benefit of this is that you can decide later how you want to crop this - vertical vs. horizontal - or even move the whole subject to the left or the right. When you're under the pressure of an open studio situation it's really easy to rush the subject placement stage of the painting. If you tape the linen to cardboard and crop later, it gives you more "wiggle room".
Also, if you completely mess things up, you can throw the piece away without having gone to the bother of gluing it to a board. If it turns out to be a masterpiece then it will be on lovely linen, and you can wait until it dries and stretch or glue it. If it turns out to be somewhere in between a masterpiece and a train wreck you can stack it or roll it up and throw it in your closet.
I think there's a lot written on the Forum about gluing linen to boards, try a search. I use Demco glue.
Oh, and not to be a noodge, but I think the ear might be too small on your painting. I just noticed it.
