UPcycled old jars

I’ve got a HUGE stash of old jars (mostly SMALL ones) that I have been saving for AGES for ‘just the right’ craft project to use them for.   THIS just might be it!  (click on the brown bold THIS to go to the tutorial)

How, if I can just FIND some of the pretty paper napkins everyone is using on crafts like this!!  All the blogs I’ve seen state they are napkins they already HAD.  Anyone know WHERE to look for napkins like this.  LOTS of craft projects to use them for.
