6lbs - well done you!
Understand totally about buying new stuff - I've got loads of things from my bigger pre-DC days that just needs me to get my arse into gear to alter. Also, if you are losing weight, the last thing you want to do is buy stuff now that won't (hopefully) fit you in a few months time.
The obi would be flattering. It would also fit you whatever size you are.
A bit of velvet ribbon shouldn't cost too much though, you'd probably only need a metre.
I think we've lost Charchar in the Bermuda Triangle that is Craftster.
