In the meantime, I have a winner to announce!
Congratulations to Kristi-Anna who said...
If it's only an evening crop, don't plan to bring a lot, b/c if you are like me, you'll just sit and chat, and not get lots done.
That said, I would perhaps try a 'theme' for your cards for that night. Perhaps do all birthday ones. that way you can bring your birthday sentiments, a few stamps that you have that you know will go well for birthday cards.
I hosted a crop once, and the lady brought card stuff... but ONLY SCRAPS!! She determined to use only scraps for her cards - yes, even for the card base itself. She came up with some fabulous cards with papers that had been torn, bits of patterned papers, punched papers, you name it!!
What does the store have for tools for you to use? You won't want to bring lots of tools when they are already there too!!
