Mason bees seal their egg tubes with mud. Those tea cups are meant to be little bird feeders, but I see no reason you can't put mud in it for the beesWhat is a mud cup?
I think mason bee housing is a great way to get your feet wet on bee keeping. Then when you feel like things are more manageable, you could move on to top bar hives and try to attract some wild honey bees. At least that I what I am going to do.
