An Opening Element or Aperture
I've made a Ruby Wedding Anniversary card and used a fancy die that I had in my stash. The ribbon holds the card closed and then when opened it reveals
The inside which is a Polkadoodles Squarey Swirly Hearts die cut from the same card with small half pearls added for extra embellishment. The nesting square is from the same set as is the heart that I've made into a tag.
The numbers are all from a the poundshop and are kind of puffy silver but are really easy to use! Good luck with the challenge!
