Stitching Blogger's Question

I finally signed up for this meme, so here is my first go at it:

When you stitch from a kit and use the supplied floss do you have leftovers? If so, how much and what do you do with them? If not, do you usually have just enough or do you have to dig into your stash to finish?

I rarely use kits, so this doesn't usually apply. The kits I have done I find that I'm holding my breath near the end that there will be enough. Leftovers would go to the girls to play with when they pretend to "stitch" or "quilt".
