Sounds really cool! I don't think it needs to be that tall - the project I just finished is 4 x 1.5 and 4 feet seems really long (tall) unless its just to refill (visually) the space, but really once the tree is gone I think you'll (anyone) will get used to not having that air space filled...just my 2 cents. Can't wait to see what happens (by the way, will April work for you for me sending semps? Cause I'm sure I could send some sooner too!)
