I really hope you do more too, Nam. I’ve got access to quite a few cardboard pieces. I could cut them for you and mail them to you. 🙂 That way all you’d have to do is slip them into envelopes. Also, you could put the drawings in plastic sleeves, that way you wouldn’t have to worry about them rubbing.
OR, Ive got some comic books that come in plastic sleeves with a cardboard piece on the back for support. Would the sketches be safe enough to mail like that? PM me if you’d like some cardboard pieces. I know I haven’t been around much lately, but I am done moving (for now) and settled enough that Ive got internet time! Whoo hoo! 🙂
