Went Junkin! Vintage Wooden Thread Spools

Did you ever see something and while you don't have any idea what you'll do with it, you just know you should pick it up? That's how I ended up with 49 Vintage Wooden Thread Spools:@) I saw two bags of them at Goodwill marked 97¢. Most of them are a little over 1" tall but there are several sizes and a few interesting shapes. None of them have thread.

 I took a picture of some of the more colorful ones...

 When I was a kid my Grandpop would hammer 4 nails into a spool and I would "knit" a long tube shape with yarn... 
I do know I'll do that with one of them:@)  What would you do with them, any ideas?

 Have a happy day!
