I interviewed at a school where I know most of the teachers. I've decided to do hand-written notes. Are neutral cards from Target appropriate? I know they say to use high-quality cards.... Also, there are a few people whose first names I do not know how to spell. Is it okay to just put Ms Last Name on the front? Their names are not listed on the district web site, and they have a staff day tomorrow so I can't ask the secretary. TIA!
