Villette --
I would not be offended at all. In fact I would rather you sell something than have it sit around in the closet taking up space. One Yorkie's outgrown dress is another Yorkie's fashion statement. In this day and time we can all use a bit of extra $$ on one end and get a bargain on the other. I say, GO FOR IT! In the sale you might generically thank all of those who "contributed" their time and effort.
