Navy yarn (silver threaded design?) and silver key charms.

Knit Mogget onto it? Or just a charter mark on the tea-tag and leave mogget for an amigurimi?

Pattern so far:

CO ?
3 rows seed stitch
Continue in single ribbing until desired length.
3 rows seed stitch.

(Possible PU and K to add pocket?)
(How am I fastening it? How do I make a strap?)

Sun 29th Apr 2012- Acquired silver/gray yarn. Finished base. Planning on silver stitched charter mark in centre, keys on either side. No key charm. Silver button, navy strap. Possibly silver edging.

Parchment ribbon instead of button? Would make it more adjustable to different sizes, but maybe not as secure? Awesome if I could print some lettering or charter marks onto the ribbon.
