Here is the "old" things I used:
Polka dot paper mat at least 3 yrs old,
Embellishment/bone- ? years,
Butterfly- recycled from a birthday card last Oct,
Grass paper-about 3 yrs,
pink and white flowered paper- 3 yrs
I know you can probably find a lot of vintage - maybe not vintage, but just plan old stash in your craft room too.
