LOL thats exactly what I'm doing Devin - putting all my "stuff" in boxes in Dad's basement saying I will deal with it one day in the maybe-near future.
I am in the process right now of selling things and I am using the "have you used/worn/needed it in the last year rule to determine what stays and goes.
Becca - I am taking clothes/shoes/bathroom things and then whatever stuff I can put in between the clothing. I have some knick-knack things that are sentimental to me (but also small), so I will wrap them in clothing or something to keep them safe. I dont plan on bringing a lot of books simply b/c of weight, but you are a bigger reader than me, I think, so that may be a harder thing for you. But I do have some that I've had since I was a kid and just like to have them on a bookshelf, so I'll bring those. I also have some drinking glasses and things and I am going to bring just because they were my parents and now I use them and love them, but again, I'll wrap them in clothes.
So, mostly, I am thinking more of sentiment than practicality or need to use the things once in England. Just think that things can be sent over to you later if you decide that you need something or if the thing is inexpensive, I am replacing it just b/c its a good reason to do so
Also, I am thinking of taking some things there when I go in two weeks, but am nervous about being pulled aside and having my luggage gone thru and it looking like I'm there to stay! I would absolutely have Tim take some things home for you - that would be a good start.
