I just stamped with white craft ink on black paper, printed my saying and matted it, then put my little sticker on it. Then you just put it in a dollar store plastic picture frame, so that the ledge is at the top facing down( it lays flatter that way for writing) Then you just stick your post it on the front of the frame. I think I'll give a pen as well. I hope it was my teacher post it that you were talking about
Hope this helps,
Shan
