I love these minature seam rippers:

I included them in Christmas gifts I gave out last year and they were a hit! I also included a cone of Superior So Fine #50 thread from the Try Me section of Superior's web site - only $6 for a 3,000 yd. cone, choice of 3 neutral colors, but they are on sale occasionally and I got mine for $4.19 a cone.
A small project bag is nice also. Quilt in a Day have them on sale often. And, of course candy and gum!
let us know what you come up with!
