T-shirt pockets are really handy. They hold things that will surely fall out as you are launching your friend's plane. Ball point pens are especially good for punching a neat round hole in a silkspan wing. (Monokote is fairly pen-resistant.)

I've learned that a Phillips head screwdriver is especially effective for "ventilating" $$$cote, kinda overkill for silkspan tho...
Bob:
I'll take a 2XL. Any chance the t-shirt company has a retro-hippie tie-dye (or is it Ty-dye?)
Otherwise, color not real important, unless you can get a kind of blissful dusty-rose...!
