Well, maybe not gardening themed exactly, but perfect for someone who is a gardening enthusiast.
Sometimes it's fun to make cards with older supplies... things that might not be the latest and greatest, or uber-trendy... but are products I still like but haven't used for one reason or another. Do you have anything like that in your stash?
Here are three cards I made using the same basic supplies and were inspired by a sentiment from Papertrey's Inside Out: Thank You stamp set.
Afterall, if you are going to take the time to pick out some supplies that go together, might as well make up a bunch of cards rather than just one.
Using up your old supplies is a good thing... think of it as a form of spring cleaning! :)
