bases for scratch built ships

I just found a couple of nifty things to use for bases! (You know...the little
posty things they sit on...)

The first, I just encountered, is called a "bow tack". It is used by ribbon
bow and rose making gadgets. The "tack" is to keep the ribbon
held togather.  Anyway it is about 1/2" tall, made of clear plastic.  I
heard these are available at craft stores in the bow making section. My source
says: You should be able to get about a hundred "bow tacks" for the cost of 3
pairs of Flat ear posts! I will have to check into this!

Anyway the other is a game piece at my local hobby store. It is about an inch
tall, comes in various colors, and several can be had for a dollar. It also
looks like a tack, with a little round ball on top.
